Re: A paludarium project
it's a 1:1 mix of sphagnum and perlite. held to position using a plastic mesh. the media will touch the water a little. not really submerged. my concern is, i read somewhere that the water used for cp should not contain minerals. so i'm worried that the water with the fishes in it will have minerals as fish poo will break into nitrite then into nitrate which in turns will work as fertilizer for aquatic plants. will this raise any concerns for the cp?
