Rash looking thing on puffers neck

[Yerxi]

not sure what it is that's on his neck but he had a swim bladder infection yesterday that i had treated with a peeled pea and now this appears, it doesn't seem to bother him but its hard to tell. Any information, identification or treatment methods would be appreciated

10 gal tank with a hang on the back filter, the ammonia is about 0.025ppm, nitrite was a little high at 2ppm but i plan on doing a water change later today to correct that, and nitrates were normal at >20ppm. Salinity is ~35%, pH: is somewhere <7.4, my kit only measures higher than that. Not sure the lighting but its just some light that came with the fish tank lid, it isn't anything special. The aquarium has been established for maybe a month or so now. Only seems like he's affected and it doesn't seem to put him under stress, he's acting normal.

The low pH s problematic, do you have a way to aerate the water to blow off the carbon dioxide, some way to agitate the surface better?
2 ppm nitrite is actually very high, but nitrite is not toxic to marine fish. It does however indicate there has been an ammonia problem preceding it, and that could have caused the skin issue.

is a product you suggest to raise the pH and to what number? I believed that the plants, wave maker and hob filter helped with that no? and yes there was a ammonia problem recently but that was a week or so ago, is there no way this could be linked with his recent swim bladder disease?

 

[Jay Hemdal]

No, first you need to determine if the low pH is caused by lack or strong aeration. If not, then you should do water changes to raise the pH since you have other water quality issues as well. Adding pH buffer is just putting a bandain on the issue.

I can't tell you the cause of the swim bladder issue.
