I have a 180 Gal I set up for Tropheus. Then being me I stocked it with Hap's & Peacocks. There are two 1400 circulation pumps ( for the Trophs). I like the job they do. Do you think the fish do, Hap's & peacock's. What do you think about running them a few hours a day to move the waste ? Or 24hr or not at all? Thanks :-?
