Im having a red hair algee thing I don't want to add anything to my tank till I get it all gone its better but not gone. got some crabs at the FS he said they will do the job but it might take awhile. the bubble was my 1st. coarl had about 10..15 bubble on it move it to the light and it took off thanks
