Yes, but the answer is a qualified "yes", Cheato wil only be able to remove those phosphates that are free in the water column, so it will have access to remove them. It will compete for these substances as will all other algae and bacteria in the tank, so depending on what is in the tank, the Cheato will get a part of it. The rest will be a part of the benthos and the surfaces of calcareous substances in the system. Each item that is a sink in your system will acquire a part, with most of these sinks only giving up their portion when there is some large change in the conditiions of the system (usually not a good set of changes). It IS an export mechanism, a good one, and I do not want to discourage its use: just be aware that it may require that you make some compromises depending on what biotope you're trying to emulate in the husbandry of your system.AlgaeMan said:Will (Cheatomorpha) remove PO4?
