Hi guys!
As mentioned in the title, I have an AIO 32G, 1.5 months old.
Lately, I am having some tiny bubbles on the surface. (See pic below)
The bubbles seem to be created by the jet of water coming out of the return pump, pushed down by the jet, like a small vortex and then they rise up and stagnate on the side of the aquarium where there is little agitation.
- I have already checked my tunze9001 skimmer (if on or off, it doesn't change; my skimmer doesn't even produce any foam, just kind of boiling water because I think there's no much to skim). I don't have any corals or fish. Just 20 inverts.
- NH3 is 0 / NO2 is 0.075 / NO3 is 25ppm / PO4 is 0.08ppm.
- There's no oily water on the surface that could trap the bubbles; (bubbles can be easily removed manually and they don't stink or leave yellowish water on the cleaning paper.
- I also tried to direct the outflow of the return pump upwards so as to create more agitation but it's still the same thing
What it could be?
