Hello! Today I joined aquariumadvice.com and I have never used a forum or chatted on line, so I hope this is posted correctly. I have a new 75-gallon reef tank that has been set up for about 5 weeks. We bought this aquarium from a previous owner and have about 40 lbs of live rock, sand, 1 powder blue tang, one psuedochromis, one sea urchin, 3 coral, snails and hermit crabs. I am about to add decorative rock and change my lighting to metal halide w/ 2 VHO
bulbs. But....I am having issues with my skimmer. I have a Red Sea Berlin protein skimmer (in-sump) and it works about 2-3 days producing white/clear foam, and then it stops working completely. Although there is thick green skimmate in the collection area, it is not draining down the tube into the collection area. I don't understand what is going on. I do feel it is working a little or else there would be no thick green stuff on the black disk like thing, but is it normal for it to produce white foam and then quit working? Is it normal to have to clean the skimmer every 2-3 days? What is this all about? Any advice would be helpful. I have called the experts @ the fish store and have looked all over the net and cannot find out what is going on! Thanks!
