whats goin on MFK , started out fresh water 6 years ago. I got bored and went to saltwater for 3 years and that became more like a second job. I have a 7 foot 200 gallon and a 5 foot 120 both in wall side by side. I am in the planning stages now, i have a 150 gallon rubbermaid sump and i plan on running both tanks from that one sump..
