How Long Does Aquarium Driftwood Take to Sink?

Let us now address the elephant in the room. What is the time it takes for driftwood to sink? In all honesty, there is no one-size-fits-all response. However, we may draw assumptions based on a few things.

Driftwoods come in a variety of shapes and sizes. However, some factors determine whether driftwood sinks or floats. So, to assist you get an idea, we’ve divided driftwood into groups. 

Driftwood soaked in water 

Driftwood, as previously said, has pores all over it. Most pores are filled with air, which keeps them floating. You may, however, remove the air from the pores and replace it with water with a little effort. 

So, how can you waterlog driftwood, you may wonder? 

Waterlogging may be accomplished in a variety of ways. Boiling, baking, and soaking are a few examples. Scraping and removing trash, and so forth. Boiling, on the other hand, is the most straightforward and repeatable method of waterlogging driftwood. 

If your driftwood is solid enough and has been properly heated, it should sink in two to seven days.

Driftwood that is non-porous and natural 

The ideal sort of driftwood for any tank is non-porous driftwood. They waterlog readily and sink quickly because they have few to no pores. Malaysian Driftwood, African Mopani, Bogwood, and other types of driftwood are examples.

They sink quickly since they don’t have many pores. However, the size of the tank and the wood, as well as the Porousness of the wood, all have a role. This kind of driftwood, on the other hand, will usually sink within the first two weeks to a month.

Driftwood that is porous and natural

This is where everything goes wrong! The pores of porous driftwood are filled with air and tannins. As a result, if you put them in your tank straight, they will float. It would sink, though, if you choose the appropriate driftwood.

They may sink for up to a few months in most cases. If you choose the floating kind, however, it will not sink regardless of the time. As a result, bear it in mind. In typical conditions, though, it will take A month at the very least.

Driftwood is used in aquariums for a variety of reasons. 

Driftwood is sometimes misunderstood as merely being good for aesthetic purposes. Driftwood, on the other hand, has a number of unspoken advantages that we frequently ignore. Here are a few advantages of using driftwood in your aquarium:


Driftwood is a source of food, which may come as a surprise to non-enthusiasts. Driftwood is a favorite food of several carp species, such as the Common Pleco. 

Because they’re little, they don’t cause any obvious changes to your driftwood when they devour your Placos. However, the quantity of driftwood they consume varies according on the Placo species. Driftwood appeals to certain Placos more than others!

pH Consistency 

It’s critical to keep your tank’s pH in check. Despite this, most aquarium owners have difficulties in this area. So, if you’re concerned about pH, driftwood could be the best solution for you! 

So, why does driftwood reduce pH, you may wonder?

Certain types of driftwood have the potential to reduce the pH of your aquarium. They have chemicals in them that reduce the pH of the water to make it more appropriate for their requirements. Malaysian driftwood and African Mopani wood are two common examples.

In addition, unlike other chemicals, driftwood has no negative side effects. As a result, they’re a natural answer to your pH problems. 

Fish-Friendly Environment

Driftwood in your aquarium might help some fish adapt to their new surroundings. Some fish like to hide in the tank, and driftwood offers just the appropriate atmosphere for them. 

This also enables you to try out different types of fish. While the driftwood offers a hiding spot for them, the remainder of the tank allows for the growth of other species. 

Your Aquarium’s Condition 

Driftwood has the greatest influence on the overall health of your aquarium. Driftwood encourages the development of good microorganisms in your aquarium. This bacterium gradually breaks down hazardous components, maintaining the health of your pond. 

Driftwood’s huge surface area also provides ample room for these bacteria to flourish. Other physiological activities, such as the development of algae on rocks, benefit from this. 

Driftwood, which is abundant in most bodies of water, gives the fish a natural feel. This lets the fish feel more at ease and allows them to adjust to the aquarium more quickly. Finally, they release tannins into the water, which assist to maintain the pond’s natural oxygen levels.


Driftwood is just what you need if you want your tank to stand out! Driftwood may give your aquarium the appearance of a riverbank. They give your tank a wonderful feeling of tranquility! 

Driftwoods such as mopani may also be utilized to secure aquatic plants to your driftwood. If you’re having trouble growing particular plants, these may assist. So, if your java moss isn’t growing, purchasing some driftwood could help.

Your water may seem darker due to the tannins in your driftwood. It’s known as the “blackwater” style, and it can really make your tank stand out. You’d be astonished at how creative some of the designs are if you’re seeking for driftwood aquarium ideas.

How to Get Driftwood to Sink Quickly in an Aquarium

It’s not difficult to get driftwood to sink. Although it may take some time, it is preferable to have them ready in your pool. Otherwise, it will float for months, causing problems for the other items in your pool.

If your driftwood drifts unexpectedly, it may harm your tank’s vegetation and wildlife. It may also be dangerous for the tank’s outside.

So, here’s a list of things you can do to get your driftwood to sink quickly:

Cure your Driftwood (method 1) 

The simplest method to waterlog your driftwood is to cure it. The tannins and air trapped in the pores of the driftwood must be removed. Curing it allows the pores to expand and fill with water. As a result, the driftwood becomes waterlogged. 

Take a big bucket and fill it with dechlorinated water to cure your driftwood. Cover the bucket with a towel and set it aside for a few days. In one or two weeks, most driftwoods will be ready for the tank.

The water may become black as a result of the tannins released by your driftwoods. If that’s the case, replace the water everytime it becomes a different color. Place it in your tank when you detect no change in color after changing the water.

Boiling Driftwood (Method 2)

Boiling driftwood for your tank is the most typical technique to waterlog it. Boiling helps the tannins drain out more quickly, causing the driftwood to get waterlogged sooner. It also sterilizes the driftwood, eliminating any potentially dangerous materials. 

Fill up a big pot halfway with water. Then throw your driftwoods in the pot and bring to a boil. If your driftwoods are of regular size, sterilizing and preparing them for the water will take 1-2 hours. 

If your driftwood is particularly huge, it may need extra support. Use something substantial, like as boulders, in conjunction with the driftwood to hold it in place. It takes a little more time. But it’s the only method to deal with difficult-to-handle driftwood.

The Reasons Your Driftwood Doesn’t Sink

Driftwood takes some time to sink in most cases. As a result, you must be patient with your driftwood. Knowing why your driftwood isn’t sinking, on the other hand, may help you fix the issue more quickly. 

The following are some possible causes for driftwood not sinking:

Driftwood Types 

The Driftwood Types you have determines whether it will sink or not. While driftwoods like the Malaysian driftwood will sink quickly, many varieties might not sink at all. Especially, when you collect your driftwood, it might not sink because of its material.

As a result, we suggest purchasing your driftwood from a reputable source. You’d know what sort of driftwood you’re utilizing in that instance. As a result, you can estimate how long it will take to sink.

Driftwood Dimensions 

This is a crucial component, despite the fact that it is self-explanatory. The longer the driftwood takes to sink, the longer it will take to sink. Additionally, driftwood that is almost as long as your tank may not sink at all.

As a result, while purchasing driftwood, make sure the size is appropriate for your tank.


The density of your driftwood is the most important aspect in determining whether it will sink or not. The easier the driftwood sinks, the denser it is. Its upthrust increases as a result of the density, pulling it down. 

As a result, selecting driftwood based on density is critical. Driftwood with a higher density sinks faster and is likewise more durable. If left in water for too long, lighter variations might become brittle and shatter.


The amount of pores in the driftwood may also affect how well it floats. The pores in the driftwood are almost always filled with air. As a result, when you put driftwood in water, the air helps it float. 

If your driftwood is too porous, it will continue to float upward until you take action. Porousness, on the other hand, may be dealt with just a few measures, unlike other concerns. 

In an aquarium, How to Keep Driftwood Weighed Down 

It’s a good idea to waterlog your driftwood while doing so. It may not work in certain circumstances. In such scenario, you’ll need to take certain precautions to protect your driftwood from sinking. To keep your driftwood in place, you’ll need to weigh it down. 

So, what’s the best way to weigh down driftwood? 

Driftwood may be weighed down in a variety of ways. Attaching heavier things to the driftwood or adhering it to the bottom are the most common methods. You must choose the appropriate stage for your tank.

Here are a few ideas for weighing down your aquarium’s driftwood. 

Place something heavy on top of your driftwood. 

Adding weight on your driftwood is the simplest method to keep it weighted down. Heavy things, like as boulders and aquarium décor, may be placed on top of your driftwood. This will hold them in place by preventing them from moving.

They’re also often tethered to the tank’s top. As a result, the tank’s weight might hold them in place. While it isn’t the safest option, it is possible.

However, it poses a significant danger to your tank. The driftwood will begin to float again if the weights are moved slightly. The fish in your aquarium may be harmed by this quick movement. We don’t advocate this unless you’re certain about the positioning.

Slate is a good material to use. 

Placing a piece of slate on top of your driftwood is the simplest and safest method to keep it submerged. Drill a couple holes in a piece of slate and use your driftwood to secure it. Place it in your tank after that. 

Choose your slate wisely in this scenario. Your slate’s weight should be more than the tank’s buoyancy. Otherwise, the slate and the driftwood will continue to float in your tank.

Make sure, however, that the screws in your tank are stainless steel. Other components in your tank may leech iron. This is bad for the health of the fish in your aquarium. 

Screws are also not recommended if your tank contains snails or other similar critters. It has the potential to obstruct their mobility and hurt them.

Driftwood Should Be Glued

If you don’t want to deal with the hassle of using a slate, you may use glue instead. Apply some adhesive to your driftwood and stick it to the bottom of your aquarium. However, this is a very technical subject. 

To begin, make sure that your substrate does not submerge your driftwood. Otherwise, it will be useless. 

In this scenario, the most significant element to consider is the quality of your adhesive. Ascertain that it is non-toxic and will not hurt your plants or animals. Also, don’t use too much adhesive or the water may get murky. 

We’ve now covered all there is to know about driftwood. And we’ve spoken about how to sink them! 


Is it okay if I utilize the driftwood I salvaged from a nearby body of water?

You can if you have a decent concept of driftwoods. However, before placing it in your tank, sanitize it and make sure it’s saturated. Otherwise, you risk causing irreversible harm.

How can you remove stains off driftwood?

If you have little stains on your driftwood, they will come out when you boil it. If the stains persist, dilute the water with vinegar. Then scrub the spots away using a steel brush. 

What is the best way to bring the color of driftwood into my fish tank?

If you want your tank to have a “blackwater” look, you should allow the tannins drain into it. If that’s the case, purchase some non-porous, natural driftwood and put it in your aquarium. You can’t get the color by curing or boiling them beforehand.
