Since hooking up a sponge filter with a relatively powerful airpump with a jet added for current, there is an incredible abundance of tiny air bubbles everywhere in the tank. These bubbles stick to my oscar and he releases parts of his slime coat when he moves.

Is this normal? The only reason I can see the slime coat coming off is because of the dozens or hundreds of air bubbles attched to it. Otherwise, I wouldn't notice. Or, could it be that he is getting stressed from this change in his environment and producing more slime?

The pictures don't show the pieces of slime or how prevalent the bubbles are, but they might offer some idea how much air gets sprayed around the tank.

Turn the powerhead off. He seems to be OK in the pic, but a video might help illustrate what you are seeing. B)

THOSE WHO REFUSE KNOWLEDGE ARE DOOMED TO FAIL.

WATER CHANGES ARE THE LIFEBLOOD OF THIS HOBBY. IF YOU DON'T BELIEVE SO OR SIMPLY DON'T FEEL LIKE DOING THEM, RE-HOME YOUR FISH, SELL YOUR AQUARIUM & FIND ANOTHER HOBBY, AS YOU WILL FAIL UTTERLY, COMPLETELY, & MISERABLY.

Can you adjust air pump? Or try reducing jet for current. I can't remember what type of filtration you have but if it is canister those bubbles will get sucked into filters and could cause airlocks. I had problems with my canister with an air stone too close to the intake.

No, I don't have a canister. I could see how that could be a problem. I could adjust the valve on the airline tubing, but it makes the pump louder. I'll turn the powerhead off for now. It doesn't happen or I can't see it happening with the powerhead off. He doesn't look or act stressed - just the opposite, in fact. It's pretty fascinating watching this slime peel off. I'll try to get a video up.

It looks like from the pic that the air bubbles are going right into the powerhead, if it is that is your problem the bubbles are being chopped up and blown around like snow creating your micro bubble situation. Move your powerhead to another location

That's excatly the case, BK - micro bubbles. I knew the powerhead was blasting the bubbles sideways, as it is above the sponge filter. But, I hadn't considered it was chopping up the bubbles. That's also why there are so many. They're so tiny they have little buoyancy and tend to stay submerged a long time as more accumulate. I'll move it over a few inches and it should clear up.

Ya those bubbles will remain there till the o2 is absorbed into the water column or brushed away

Are micro bubbles like that harmful to fish? ... beyond this issue with the slime coat shedding.

Other than being an irritant to the fish and looking kinda annoying its pretty harmless, they have been know to cause other issues with more sensitive fish like discus and angels but when i kept both i never had a problem
