Okay, so I have a 12 gallon salt water tank. It has a condy anenome, 2 firefish, 3 or 4 snails, a starfish, and a bunch of seaweed. I also have a few button polyps. It is cute, but it just isn't that pretty. I have had it since last december. But anyways, now that you know my background in saltwater, I have a question - I want to convert my 55 gallon tank into a saltwater tank. I have cleaned it, it is ready to go. I have planned to make 2 sumps/refugiums from two ten gallon tanks. My problem: How do I get the water from the big tank to the 2 smaller ones. I have thought maybe to let it siphon, but I don't think that will be good enough. Please help!
