Hello MFK member's. Been reading for awhile first time post. I used to be a commercial fisherman in the great lakes for 10 years, which has recently started me to keeping fish at home with my daughter. It started as usual with a 2.5 gallon hex tank with a betta, and has grown since then. Eight tanks later I currently have a 75 gallon divided betta community tank, a 125 catfish and fire eel tank and two 20 gallon shrimp feeding/breeding setups. Until now my recent purchase of a 325 gallon all glass tank in need of restoration. So thanks in advanced for all the info I will require to make this big predator(?) tank happen.
