I have a serious problem with bubble algae that I need some help solving (before anyone asks my nutrients are very low and the lights are only on 8 hours a day). I have tried emerald crabs and they have either done nothing or worse yet they pick at my SPS polyps. I had a pitho crab that put in some real work but he died and I'm having a hard time sourcing another one right now. Does anyone know of any other reef friendly bubble algae eaters that would fit in a 35 cube tank (don't want to resort to using Vibrant as I've had some friends who lost corals using that stuff). I've heard rumors that tuxedo urchins, lettuce nudibranch, and turbo snails will eat it can anyone confirm?
