Ok had this thing on the tank since Mar. The micro bubbles were there at the start but went away. Well we had a red slime problem and after cleaning alot of the algae out of the diffuser cup it is now making bubbles like mad and wont stop. I see people suggesting drilling more holes in the bottom of the cup and another suggestion about getting rid of the cup and using a foam filter at the base of the outlet tube. Which of these do I need to do to stop all these micro bubbles from pouring into the tank? It looks to me like some are coming out of the slits at the bottom of the cup and the rest are pouring over the side. Any help would be great everything looks very unhappy with all those bubbles in the tank.
