my tank has been established for about 7 months. It's a mixed reef. Is the cost worth it to go from my two hob filters and hob skimmer to a sump with a hang on back overflow? The hang on back over flow looking at is at marine depot and has a continuous siphone. Is this worth up graded to and adding a refugium?
