How To Weigh Down Driftwood In An Aquarium

Imagine having a fish tank that looks like a cozy home for underwater buddies. Driftwood is like a fancy decoration that makes fish feel at home and looks really nice. 

But guess what? When you put driftwood in the water, it can be a little mischievous and try to float instead of staying down.

But don’t worry, I’m here to help you out. In this guide, I will teach you some tips to prevent driftwood from floating in an aquarium. Additionally, I will also explain how to weigh down the driftwood.

This way, you can make your fish tank look like a magical underwater world. So, let’s begin.

Driftwood Serves Multiple Purposes in Aquariums

Before we dive into the methods of keeping driftwood in place, let’s unravel the amazing roles it plays in your underwater world:

  1. Natural Beauty: Driftwood brings a slice of the outdoors into your aquarium, making it look like a mini underwater forest. It’s like adding a touch of nature’s art to your fishy haven.
  2. Secret Hiding Spots: Imagine you’re building little forts for your fishy pals. Driftwood does just that! Shy fish or ones that like their space can use the nooks and crannies of the wood to hide and feel safe.
  3. Tasty Biofilm Buffet: Driftwood sets up a buffet of tiny, helpful organisms called biofilm. Some fish and critters love snacking on this invisible treat, which helps keep them healthy and happy.
  4. Water Magic: Certain driftwood types work like underwater wizards. They release tannins – like a natural potion – that can change the water’s chemistry. This is like giving your fish a taste of home by mimicking their natural habitats.

Driftwood isn’t just a decoration – it’s a multitasking superstar in your aquarium. From creating beautiful scenery to offering cozy corners and even playing a part in your fish’s health, this wood works wonders underwater.

1. Using Ties is Common

If you want to stop your driftwood from floating around in your aquarium, here’s a simple way to do it: 

Get special ties that are safe for your fishy friends. These ties can be made from fishing lines or nylon thread. Take the driftwood you like and wrap the tie around it. Make sure it’s snug and won’t come loose. 

You can also tie the driftwood to big rocks or decorations in your aquarium. Make it tight so the driftwood won’t pop up. 

Now, gently put the tied driftwood back in the water. The tie, along with the weight of the rocks or decorations, will hold the driftwood down under the water. Remember, be gentle when wrapping and placing the driftwood to keep everything safe and sound.

2. Securing Driftwood with Glue: Easy and Safe

Using glue is another clever trick. Here’s how you can do it:

Choose special glue that’s safe for your fish and aquarium. Look for something called “aquarium-safe epoxy” or “silicone glue.”Take the driftwood you like and apply the glue to the parts that will touch the rocks or the bottom of your aquarium. This glue acts like a strong bond that keeps the driftwood in place.

After applying the glue, be patient. Let it sit and cure for a while. This usually takes a day or two. It’s super important to wait until the glue is completely dry and hard before adding your fishy pals.

Once the glue is all set, you can gently put the driftwood into your aquarium. Your fish can swim around it without making it come loose.

Using glue to hold the driftwood down is a smart way to keep your aquarium looking awesome. Just remember to use the right glue, let it dry well, and then let your fish enjoy their new hangout spot.

3. Use of Weights

You’ll need some small weights or sinkers, which are like little heavy things. These are usually easy to find at the aquarium or fishing supply stores.

Take your driftwood and tie the weights to it using specialties. Make sure to tie them in different places so that the weights are evenly spread out. This helps the driftwood stay balanced in the water.

When you put the driftwood back into your aquarium, those weights will work their magic. They’ll stop the driftwood from tipping over or floating up to the surface.

By adding weights to your driftwood, you’re making sure it stays right where you want it. Your fish will have a cool new spot to explore, and your aquarium will look even more awesome. Just make sure those weights are tied tightly so everything stays safe and secure.

4. The Utilization of Stones

When it comes to stopping driftwood from floating around, stones can be your best buddies. Here’s how you can use them: 

Look for larger stones that are safe for your aquarium. You want ones that won’t harm your fish or the water. Take your driftwood and carefully tie it to the stones. You can use special ties for this. Make sure the ties are tight and secure so that the driftwood won’t come loose. 

Now, put the driftwood with the tied stones into your aquarium. Those stones will act like anchors, holding the driftwood down in the water. 

With the stones helping out, your driftwood will stay steady and won’t float away. Your fish will have a comfy new nook to hang out in, and your aquarium will look even more fantastic.

5. Driftwood and Plant Pairing

Choose some live aquarium plants with strong roots. These roots will help hold onto the driftwood and keep it from floating away. Take your driftwood and gently tangle it up with the roots of the plants. 

Put the entangled driftwood and plants into your aquarium. The plant roots will grab onto the wood, making it stay put in the water.

This partnership between driftwood and plants not only keeps things stable but also adds a touch of natural beauty to your underwater world. Your fish friends will love exploring this new hideaway.

6. Use Fishing Lines to Tie Driftwood Together

Choose a couple of pieces of driftwood that you like. It’s like making driftwood friends. You know those thin, strong lines people use for fishing? Grab some of those. They’re great for this job.

Gently wrap the fishing line around your driftwood buddies. Make sure it’s snug but not too tight. This way, the pieces will stick together, and they won’t float away.

Put your tied-up driftwood back in the aquarium. Now they’re like a little driftwood team, and they’ll stay put, creating a cool, connected structure underwater.

By teaming up your driftwood pieces, you’re making a bigger, more stable decoration for your fishy friends. It’s like a floating-fighting alliance.

Using fishing lines to tie your driftwood buddies together is a fantastic way to add both charm and stability to your aquarium. The pieces become pals, and your fish will love their new, roomier hangout. 

7. By Soaking

Get a bucket – a big one that can fit your driftwood piece inside. Put your driftwood into the bucket, making sure it’s completely covered by water. Now, grab something heavy, like a rock or a brick, and gently place it on top of the driftwood. This weight helps the wood stay underwater.

Let your driftwood soak for a while. You’ll need to be patient here. As the wood takes in water, it starts getting heavier. Change the water in the bucket every now and then to keep things fresh. 

After some time, you’ll notice your driftwood is becoming waterlogged. It’s like it’s getting full of water and heavy enough to stay down.

Once your driftwood feels heavy and water-soaked, you can put it back in the aquarium. Now it’s ready to settle at the bottom, just where you want it.

Using the soaking method takes a little time, but it’s worth the wait. Your driftwood will sink down like a champ, adding a natural touch to your underwater world. Just remember to change the water.

8. Hot Bath for Driftwood: Boiling Method

First, take your driftwood and place it in a large pot. Fill the pot with water until the driftwood is fully submerged, creating a cozy hot tub for the wood. 

Place the pot on the stove and turn on the heat. Allow the water to gently boil, like a magical potion that helps the wood absorb moisture.

Once it’s boiling, let the driftwood simmer in the water for a few hours, allowing it to fully absorb the moisture. It’s like letting the wood get comfortable in its warm bath.

After the driftwood has enjoyed its bath, turn off the heat and let everything cool down. Ensure the wood is safe to touch before proceeding.

Now that your driftwood has had its warm bath and cooled down, it’s ready for its new home in the aquarium. Place it in the aquarium, and it will settle at the bottom, staying exactly where you want it.

9. Using the Method of Drilling Holes

Here’s a hands-on approach to make sure your driftwood stays firmly in place. It’s like giving your wood a special, customized seat in your aquarium.

Find a drill – it’s a machine that makes holes in things. You’ll also need some stainless steel screws or hooks, which are like sturdy, metal hangers.

Look at your driftwood and think about where you want it to sit in the aquarium. Imagine it like choosing the best seat for your wood. Carefully use the drill to make holes in the driftwood. Think of it like giving your wood little pockets where the screws or hooks will fit.

Now, take those stainless steel screws or hooks and put them into the holes you made. It’s like creating a secure seatbelt for your driftwood.

After you’ve attached the screws or hooks, gently lower your driftwood into the aquarium. The screws or hooks will hold onto the wood, keeping it from floating away.

Using this method is like crafting a special space for your driftwood. The holes and anchors give your wood a solid spot to rest in your aquarium. It’s like making sure your wood has a comfortable seat that won’t wobble or move around. 

Remember to be careful while drilling and give your driftwood a stable new home underwater.

10. Picking the Right Driftwood

Just like choosing the right puzzle piece, selecting the best kind of driftwood matters. It’s like finding the right fit for your aquarium. Let’s see how:

Some driftwood is lighter, and some is denser – which means it’s heavier. Look for kinds like Malaysian or Mopani driftwood. They’re like the heavyweights of the driftwood world.

Denser driftwood sinks more quickly. It’s like it’s ready to dive into your aquarium right away. So when you’re picking driftwood, go for the ones that feel a bit heavier.

When you use denser driftwood, you won’t have to wait as long for it to sink. It’s like having a friend who’s always up for an adventure!

By choosing the right kind of driftwood, you’re making things easier for yourself. Denser types like Malaysian or Mopani are like the perfect team players – they’re ready to go underwater and settle down quickly.

So, keep an eye out for these heavyweights when you’re picking your driftwood.

11. Sticking Driftwood with Suction Cups

Look for special suction cups that are safe for your aquarium. These are like little cups with a superpower – they stick to glass.

Take the suction cups and attach them to your driftwood. You can space them out along the wood’s length. It’s like adding tiny holders that will grip onto the glass.

Now, put the driftwood with the suction cups into your aquarium. Press the cups against the glass bottom – they’ll stay put and keep the driftwood from floating away.

With these suction cups lending a hand, your driftwood will stay right where you want it. Your fishy pals will have a cool new feature to explore, and your aquarium will look even better.

Using suction cups is a smart way to give your driftwood some extra support. It’s like having a trusty assistant helping your wood stay grounded. Just make sure those cups are firmly attached to the glass, and your wood will be all set for its underwater adventure.

12. Sturdy Base with Slate Tiles

Imagine giving your driftwood a solid foundation – that’s what slate tiles can do. They’re like trusty platforms that keep your wood steady in the water. Here’s how it works:

Look for flat slate tiles that are safe for your aquarium. These tiles are like strong, flat rocks that won’t hurt your fish or the water. Take your driftwood and put it on top of the slate tile. It’s like giving your wood a safe and secure seat.

Now, gently put the driftwood with the slate tile into your aquarium. The tile acts as a solid base, preventing the driftwood from floating away.

With the slate tile under your driftwood, it’s like having a firm grip on things. Your wood won’t wobble, and your fish will have a cool new spot to explore.

Using slate tiles is a smart way to make sure your driftwood doesn’t budge. The tile acts like a strong, reliable friend that holds your wood in place. 

Your fish will love their new hangout, and your aquarium will get a dose of extra style. Just be gentle when placing the driftwood and tile combo into the water for the best results.

Factors That May Prevent Driftwood from Sinking

Ever wondered why some driftwood seems to prefer floating? 

Well, there are a few reasons for this, and understanding them can help you choose and prepare your driftwood better. Let’s dive in:

  • Different Driftwood Types: Just like people, driftwood comes in all sorts of types – some are lighter, and some are heavier. Lighter types tend to float more. So, when picking driftwood, think about its weight. It’s like matching the right ingredients for your dish.
  • Size Matters: The size of the driftwood also plays a role. Smaller pieces might be more likely to float because they’re easier to push up by water. Bigger pieces, on the other hand, have more weight, making them sink faster.
  • Initial Dryness: Driftwood that’s super dry will take longer to sink. It’s like a sponge that needs time to soak up water. So, if you’re using dry driftwood, you might need a bit more patience.

When you’re picking driftwood, think about its type, size, and how dry it is. It’s like putting together the right puzzle pieces to create a beautiful picture. By considering these factors, you’re setting the stage for driftwood that will happily settle down in your aquarium. 

What is The Average Time it Takes for Driftwood to Sink?

The time it takes for driftwood to sink depends on a few things, kind of like how different roads lead to different places. Let’s break it down:

  1. Wood Type: Just like people have different traits, driftwood types have different densities. Some are light, while others are heavy. Light ones might float around longer, while heavier ones sink faster. It’s like how some friends show up early, while others take their time.
  2. Methods Used: The tricks you use to get driftwood to sink also play a role. Soaking, boiling, tying – they all have their own clock. It’s like taking different routes to reach a destination.

Because of these factors, the time it takes can be quite flexible. It might be a few days, or it could stretch to a few weeks. So, don’t be surprised if your driftwood takes its time to get comfortable in your aquarium. 

Just be patient, and soon enough, it’ll settle in like it’s always been there, creating a beautiful underwater scene for you and your fishy pals.

Most Efficient Way to Remove Stains from Driftwood

As time goes on, it’s normal for driftwood to pick up some not-so-pretty stains. But fret not – there’s an efficient way to make it look brand new again.  Here’s how:

  • Begin by creating a mixture of water and hydrogen peroxide, a friendly liquid with stain-fighting powers. Let your driftwood take a soak in this mixture, almost like it’s enjoying a relaxing bath. 
  • After the soak, grab a soft brush and gently scrub the wood’s surface. Think of it as a gentle massage for your driftwood, getting rid of those stubborn stains. 
  • Once you’ve pampered your driftwood, give it a thorough rinse with plain water. This helps wash away any remaining mixture. Finally, let the wood dry out completely.
  • Now, your driftwood is all ready to return to its place of honor in the aquarium, looking spotless and rejuvenated.


To sum it all up, driftwood is a true gift to your aquarium, but keeping it anchored in place takes a bit of know-how. 

By carefully choosing driftwood that sinks quickly, using nifty methods to secure it, and patiently allowing it to settle, you’re sculpting a mesmerizing underwater world for both you and your aquatic companions to relish. 

So, revel in your beautifully adorned aquarium, and let your fishy friends explore their new, natural wonderland – a testament to the harmony of nature and creativity.


Can you put driftwood straight into the aquarium?

Absolutely, you can add driftwood directly to your aquarium! But there’s a trick – choose driftwood that’s already waterlogged or heavy. This helps it sink without a fuss.

If it still wants to float, you might need to use some clever methods like tying, gluing, or using weights to keep it down. Remember, patience is key as the wood gets comfortable in its watery home.

Does driftwood cause algae?

Driftwood can be friends with algae, but it doesn’t mean they’ll always hang out together. Algae might grow on the driftwood because it’s natural and provides a surface for algae to cling to. 

But you can control this by keeping your tank’s lighting, nutrients, and water changes balanced. A bit of algae isn’t bad – it can even add a touch of natural beauty to your aquarium

How do you seal and protect driftwood?

Sealing driftwood is like giving it a shield against water and decay. You can use aquarium-safe sealants or coatings. Before applying, make sure the wood is clean and dry.

Coat the driftwood and let it dry well outside the aquarium – it can take a few days. After that, you can introduce it to your aquarium with peace of mind, knowing it’s well-protected.

How do you waterproof driftwood?

Waterproofing driftwood means making sure it doesn’t get soggy and fall apart. You can use sealants or coatings, like those used to seal wood decks, but make sure they’re aquarium-safe.

Coat the driftwood evenly and let it dry completely before putting it in the water. This way, your driftwood stays strong and adds charm to your underwater world.
