Good to know
Don't rinse a bio-substrate and don't let the bag dry out — the bacteria live in the water it ships in.

How a bio-substrate cycles a tank
A new tank has no bacteria to turn fish waste into something harmless, so ammonia builds up for weeks. A bio-substrate carries those bacteria in from day one: pour the wet bag in, keep the water it came with, and the colony is already working.
Aqua Natural uses a blend of nitrosomonas and nitrobacter — the two groups that break ammonia down and convert it to nitrate.
Reviews by real customers
Pre soaked
No need for soaking, it is pre soaked exactly as it says on the bag. It is a good size to cover just a layer over fluval stratum in a 10gal tank, but if you want more sand I recommend getting 2 bags. It is very effective and does help keep the soil down. It looks very clean and is worth the money.
Haylise · August 2026Super fine sand!
This sand is amazing. It looks great but what's even better is that it makes cleaning waste with a net easy because the sand grains are so fine they fall through the mesh. Excellent product.
David · August 2026Good aquarium substrate
I really like this substrate. The white sand looks very clean and beautiful in the tank. I didn’t wash it; I added it directly as it came. At first, the water got a little cloudy, but the next day it was already crystal clear thanks to the filter. I also like that it comes with beneficial bacteria to help start the aquarium cycle.
