Funny story. I had red bubble algae just come up out of know where. I tried everything, a close friend of mine his dad owns a fish store for about twenty eight years now. We tryed emeralds it seemed like they were doing little bit, we scrubed and everything else we could think of. Well I had to move so in the mean time we broke everything down and he held all my live stock, and he cleaned and scrubed my rock and kept it nice. I set my tank back up in my new home and it all came back with in mounth. I always wanted a yellow tang but always a little leary of them, so in his store he had a nice one and I got the courage to try one, well with in a week all the red bubble algee was gone and it still hasent come back. Now im not saying they will help, but I had it over a year even broke the tank down for about two mounths and it still came back. Im still not sure if its because of him or just went away, im still looking for answers lol Just wondering if anyone ever hurd of anything like this.
