Well so far we have 8 tanks up and running for the "project". 60G, 55G, 2 - 20G, and 4 - 10G tanks. we currently have RCS, high grade CRS's, snowballs, and blue pearl shrimp. We are using all the 10G tanks to selectively breed the higher grade CRS's. We are running a
canister filter on each tank so as to not have a "crash" if we were to use a central filtration system. The only issue was the Aquasoil Amazonia...it can get quite expensive to cover the bottom of all those tanks...8 - 9L bags to be exact and that stuff is not cheap...
