Good day all, My name is Vic Brincat. This is my first post to 3Reef Looking forward to reading the many valuable posts here ..and hoping that I can even contribute to some. I have a couple of mixed reef tanks, a 370g and 75g running off the same system (1 x 120G sump) and using common equipment like skimmer, carb reactor, GFO, dosing, etc. The big tank is about 1.5 years old and is just staring to really stabilize and grow some decent corals. Of course, even after owning marine tanks for many, many years...I'm still learning. Hopefully, soon I can start sharing some of my own experiences...mostly on what you should NOT do..;-) Best wishes. V.
