Should I put soil underneath Flourite?
I bought a bag of Seachem Flourite Black. Since one bag is not enough, should I add soil to the bottom and cap it with the Flourite? I can get UNS Extra Fine Soil locally. Looks more like pellets than soil but read good reviews on it. This will be my first planted tank so I don’t want it too complicated plus it is low tech. Aqua soils are too expensive and I am trying to avoid pH issues down the road.
What do you suggest? Just get another bag of Flourite Black? I will be trying Monte Carlo for carpet and other low tech plants. I am shooting for 2.5-3” substrate. Height from substrate to lights should be around 12-14” depending on which light I get, most likely the Chihiros WRGB, maybe the Twinstar S.
I have purchased the flourish exel, comprehensive and small bottle of flourish advanced.
Should I add the osmocote or avoid using it? Adding it first before topping with the flourite or other soil like UNS?
