I am new on here but have bin in reefing going on two years now. Started off with a 30 gallon tank. Did some stuff wrong but I think we all have no sump and all that good stuff. Tanks still up and running good and building a 75 gallon with sump. Home made stand soon to be home made canopy. If u see anything I can do better let me know thanks.For the new tank I have vertex omega 150 protein skimmer, two 1' vertex Illumina , one vortech MP40w es... Thinking about a MP10 so save some cash for the other side. Speed wave DC return pump, Has 6 speed setting. Still a lot more to go. what ATO are any of you guys using ?.
