I am currently converting a six foot 120 gallon tank into a Kitumba Frontosa Tank. 10 Kitumba Fronts, 4 Black Calvus, and 6 petricolas. I plan on using Eco-complete cichlid sand as substrate, a Rena XP4 canister filter for filtration. I'm wondering if anyone has any suggestions or if there is anything else I need to add?
