Hello after looking around a lot of forums seems that this is the best form to post on for good answers. I have had a Biocube for about 5 months; I’m really frustrated with it for the following reason after 5 months I’m just starting to get coralline algae. I do a 10% water change every week with box water from Blue Ocean; my tests come back perfect with the PH sometimes being a little bit on the low side but nothing to panic about. All my fish survive fine and are doing great. I know most of my problem is the lighting on the tank and after 5 months I decided to bite the bullet and get the mod kit with nanotuners. But before I bought that I decided with having 5 fish in the tank I would get a skimmer. After looking all over forms I decided to get the CPR SR3 skimmer. I have it installed, and I have it tuned to what I think is the perfect setting just little bit of bubbles and foam spitting out the top with hardly any water collecting in the cup. Water lvl is perfect to the 45 degree angel they suggest. But I have had it going for a week and still all I get is a tank full of so many bubbles you can barely make out the fish. I did replace the blue crap with some crushed up live rock. The sponge in chamber 3 is all the way down. I have tried every tip in the world and still getting bubbles. I only use box water for my changes and keep everything perfect the best I can. But after all this time I’m still at a lost and so confused on what to do HELP<o></o>
