I am setting up a 75g tank with Malawian c's and have a few questions -appreciate any help that can be given.
I want to use a sand substrate - is silica sand or play sand best ?
Also, was planning on using a rounded smoother rock but worried about stacking these 15" high without sealing together...any suggestions?
How much additional maintenance and adding chemicals is there by not using Holey rock or the special Cichlid substrate to help buffer the tank?
Loads of other questions, but the pet store said a Fluval 405 would be enough filtration and most everywhere I read it says more is needed. If so, would adding a good internal filter be enough? Thanks!!!
