peat moss as substrate?
i have a 20g long that is home to a checkerboard cichlid (just a male right now, i'm waiting for a female to come in) 16 ember tetras, and a blue fan shrimp. i do water changes with peat moss tea. it is semi-planted with a large pea gravel substrate right now. i intended to only have crypts, java fern, anubias, and java moss. all plants that do well in low tech tanks and 3 of the 4 are epiphytes anyway. but i wanted to add a better substrate only in certain parts of the tank for the crypts.
could i put peat moss mixed with sand in the bottom, then sand on top to keep the peat from getting mucked up, then put my gravel on top of that?
