I recently became aware that cat litter can be used as an aquarium substrate. This interested me as I wanted to increase the height of my existing fine gravel substrate only to find it's out of stock. So my thoughts turned to maybe getting something cheap to go underneath the existing gravel. So when I came across references to cat litter being a cheap option it seemed like the ideal solution. CEC is not high on my priority list but hey if it works it's a bonus. So which cat litter to buy? I found a brand being used by a UK youtuber and ordered some. I was expecting it to be comprised of hard lumps of baked clay something like pea gravel size. Instead appears to be at least 50% dust..!
I did read it may not be successful underneath as it has a tendency to rise up to the top over time. However I will be testing this in a spare tank with no fish and am interested in seeing how it works on it's own too.
Questions: Have I got a suitable cat litter for my project? If not can someone recommend a more suitable alternative? If this stuff is okay, am i supposed to somehow separate the dust and dispose of it or does it all go in?
The brand I used also had a lot of dust, which made it a bit tricky. It did end up rising to the top over time, as you’ve read, so I ended up switching to a different option.
From my experience, I tried using a similar non-clumping clay cat litter for a tank setup, and I found that it did have a lot of dust, just like yours. The dust can be a bit of a hassle because it can cloud the water and might rise to the top over time.
In my case, I ended up sifting out as much of the dust as possible before putting the litter in the tank. It didn’t completely eliminate the dust issue, but it did help a bit. If you’re still seeing a lot of dust, you might want to consider a different type of cat litter or even a different brand that’s known for being more coarse and less dusty.
By the way, while exploring different substrates, I looked into sphynx kittens for sale for a friend. They have such a unique look and are very affectionate, which made me curious about different types of pets and their needs.

It’s intriguing that you’re considering using cat litter as an aquarium substrate. While it’s definitely a cost-effective alternative, the high dust content in the brand you ordered is a concern, especially since it could cloud the water or create issues for your aquarium’s filtration system. The fact that the litter might rise to the surface over time is also something to keep an eye on. Testing it in a spare tank first is a smart move—this way, you can observe its effects and decide whether it’s suitable for your main tank without risking your fish. CBD for Cats
