Brita previously stated specifically that its filter output should not be used for aquaria. I don't know if that prohibition still applies, but I would not use it without confirmation.
Well I did not know that about Brita. Good to know. I assume they don't want to be held responsible for any dead fish but maybe they know something else about the quality of their water.
Brita is combo carbon and ion exhange resin. I went to a Brita site and could no longer find the warning they formerly carried, rather they now suggest its use for fish. But I will still pass, thanks anyway.
