Sounds like you have a dinoflagellate problem, yuk! My tank has just gone through that problem. You can do water changes and turkey baste until the cows come home, but that won't fix the problem IMO. Finally I turned off the lights and cut back on the feeding. My lights (30 gallon tank, 4 39 watt T5's) were off for 3 days. Then I started the lights back on slow, I have been increasing both ends of the times by 30 minutes each day, so 1st day lights on 11:00 AM off 11:30 AM - lights on 8:30 PM off 9:00 PM, day two lights on 11:30 AM off 12:00 PM - lights on 8:00 PM lights off 9:00 PM and so on and so on. Feed the tank lightly even the during the days that the lights are off. Dinoflagellates (bubbles trapped in algae, followed by red slime algae)are hard to rid, good luck, BTW it has worked great on my tank.
