I will be setting up 75 gallon sps tank. Want to do sumpless tank because I don't want to deal with any the cost, noise, leaking issues with overflow and sump. Will be using two Koralia 3 powerheads and HOB skimmer along with Live Rocks for flow and filtration. For ATO, I will be using Aqualifter on a timer to perform daily auto top-off. Sensor ATO didn't work for me in the past when the sensors malfunction. Anyone running successful sumpless setup?
