With PFS, the poop will not settle into the sand, it's too fine. The bacteria that will form in the sand will convert the ammonia from the poop, and may break it down on the surface over time, but with PFS, I would be actively vacuuming on a regular basis. This also reduces the likelihood of algae by removing waste, as algae will happily feed on whatever is being released by the shrimp poo.Hello folks,
I am setting up a very small tank with only two small plants, a marimo, and 3 shrimps. Right now it's getting "cycled". It has pool sand for now, but I might switch to a finer sand for a different color. For now, I want to avoid the buffering issues involved with more active soils.
My question is what happens when the shrimp poop into this gravel? Do I count on some kind of bacteria to eat it all up? Or am I supposed to vacuum it occasionally? In the end, I want a very "clean" and sparse looking tank that doesn't have a lot of (visible) algae growth. Maybe even use white sand. What I want to avoid is that if I ever poke into the gravel it's going to release some huge bacteria cloud or ammonia spike or whatever.
PS: if the thread title is funny, it's due to a forum bug
As far as poking the substrate and causing a problem, there's no issue there.
