Co2 at surface build up
My Dwarf Gouramis has been gulping alot lately. This is not normal. I initially thought it may be due to injecting co2 even though he has lived in the tank for more than a month and a half with out issuer before. I turned off the co2 and went to use an air stone. I found my pump no longer worked. It was late so I could not get another one. Sadly he didnt make it through the night. If co2 was the culprit and not another issue. Would a layer of gas built up on top of the water from off gassing caused him to suffocate?
I have a standard 29g tank. I have a c-220 canister filter. The outflow does not create the best surface agitation and I get a light oil slick. I will be trying some ways to help that tonight after I take a trip to the hardware store. Should I run an airstone at night just to be safe? none of the other tankmates seem effected at all. That leads me to believe it may be an underlying issue with him. A local store owner mentioned it could be parasitic as he showed no outward signs other than behavior and a slight belly bulge.
All my water parameter tested normal at:
Nitrate: 10-15ppm (ferts.. If I skip fertilizing for a few days its near zero)
GH seems to be the only thing high but it has been this way for the entire tanks life.
any Ideas, thoughts and suggestions are always welcome.
