ok so right now i have a 125g african cichlid tank set up, only has like 3 pairs and 2 singles of mainly mbuna cichlids and then 2 pictus cats, so originally was thinking that when i moved it to my new place (its at my parents house at the moment but i am the only one that takes care of it so am going to move it to my new place) that i would just revamp it and put down sand substrate (has gravel right now) and do drift wood and stone deco, however i have been looking at different kinds of setups and different kinds of fish available to freshwater and think a nice blackwater setup would look really good in this tank but have no experience with maintaining special water chemistry (usually just test to make sure no trites, trates or ammonia and fish have done well) was thinking of either doing some kind of predatory tank or maybe a discus tank (they do blackwater as well right?) also i know ill have to get rid of the cichlids but would the pictus be ok with this new water? and how exactly do you maintain the water chemistry? i saw that drift wood would help release chemicals for water but what other additives are needed? sorry this is so long but new to this whole black water amazon thing and any advice would be greatly appreciated, also only filter i have on it right now is a rena xp3 and it keeps water at great levels but would i need to add another filter?
