Hi, i have a 55g reef, i have 2 clowns, 1 coral beauty, 1 tang, 1 damsel, and a cleaner shrimp. I'm using crushed coral, maybe 2-3 centimeters, i have around 1 pound per gallon of live rock. Now for issues...I have a prizm protien skimmer that like to produce bubbles, aquaclear 300 that produces lots and lots of bubbles, and a magnum 350 that makes lots of bubbles(i have to clean the microcartridge every second day to get rid of them). So im stuck with a tank thats full of bubbles, i could stop using the 300 but i think i need to use it, i don't think the magnum does a good enough job. :frustrat: Maybe i should take the foam out of the aquaclear and put 2-3 of crush coral in there and use it as a refregium ? but i'll probably still be stuck with bubbles....How can i fix these things ?
