Features:
- Flourite Black Sand is a specially fracted stable porous clay gravel for the natural planted aquarium.

- Most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. Gravel modifiers such as laterite are not necessary.
- Flourite Black Sand is not chemically coated or treated and will not alter the pH of the water.
- Flourite Black Sand is good for the life of the aquarium and need not be replaced.
- Although it is pre-washed, because Flourite Black Sand is a natural product, it may become dusty in transit and require rinsing before use to remove any residual dust.

I'm convinced they're selling fake marimos online that's why they create tons of hair algae in your tank. I kept them for so long because my corydoras and shrimp love them. But I have recently gotten rid of all of them now.

I wouldn't use substrate for a RES. They eat everything and sand can cause impaction.

Additionally the chips in the non sand substrate allow for oxygen and gasses to be exchanged which prevents anaerobic decomp from occurring in your substrate that could bring diatoms or worse, dead fish.
Any aquarium product you buy should be tailored to your lifestyle and the design of the tank.
I hate gravel vacuuming and any care in general so I buy the larger fluorite substrate, have tons(thousands) of Malaysian trumpet snails, and a heavily planted tank.
I'm also running tons of air into the tank and the water is circulated completely every minute or so via chemical and biological filtration. I do not use any mechanical filtration outside of prefilters and sponge filters which are more biological than mechanical imo. Gotta keep the snails from killing my canister filter.
I do water changes once a month and clean the filter every 90 days. Other than that they only get food. If one of the fish die the snails will remove it in under a day anyway.

Dealing with the same issue, I had 6 "marimo balls" in there and each month I pulled out about a quart sized ball.
