Ok i have one magdrive12 one 18 which feeds my skimmer and is dialed way back one unknown submersable pump that feeds my uv sterilizer. And i just ordered a ultralife Ultra Zone 360 ozone unit that ima have running threw a DIY reactor. that needs another pump. Needless to say this adds alot of heat to my tank. So i want to have 1 external pump to run them all. My tank runs 79-81 degrees but mostly at 81. Little to close for comfort with my sps even though its been like this for 2 years.150 total volume tank. im just ready to make the plunge for a good silent high quality pump. it will be in my living room. Any and all advise with personal experience is needed
