A cool side affect of skimming wet is that I believe I don't need to do a water change nearly as often. Well in the formal sense. Right now I am skimming between 5 and 7 gal. a week and replacing that with fresh saltwater. Basically my skimmer is forcing me to do regular water changes on a daily basis. I have been running my BB for about a month now and everything looks great. I am really happy. I haven't cleaned my glass since I added livestock (3 weeks).
