My preference is to avoid pushing more than one variable at a time. You will be pushing thermal tolerance some if in Alabama even without heater. Summer heat normally more problematic unless your tanks well shaded. Water quality will potentially be all over the place with confines of totes that are not ideal for being self-cleaning. Making them self-cleaning has not been properly demonstrated for me as of yet, round tanks much better. I make diets too, although not with intent of selling them. Most of the diets are specifically for Bluegill and used to determine requirements for particular nutrients or ability of a given combination of feed-stuffs to meet those requirements. If diet used is not in excess for all nutrients relative to requirements, then pushing system will not allow finding what needs to be tweaked in your culture system.
