This may be a stupid question, but are the micro bubbles put out by a protein skimmer harmful to the fish? Im in the process of calibrateing and getting it running smoothly and there are tons of bubbles. Dont know if they affect the dissolved oxygen levels or anything like that. Ive been doing small water changes to help with the bio load issue and i removed the carbon filter and replaced it with a mesh bag of ceramic filter media. The skimmer is a HOB 3 chamber model with a UV filter also. Brand Aquatop PSE 1. Any help is appreciated!
