Was running two aquaclear 110s on my fowlr 90gal, 120lbs live rock and 9 two inch fish for about a year now with no sump and had to constantly scrape glass. Picked up the cpr twin HoB skimmer setup on ebay used gir 80 and ditched the ACs. Running for two days now and my water has never been cleaner w no algae buildup
