Over airation

[lisa]

I've just noticed that one of my axies is scratching at her gills, I'm giving her salt baths, incase its an infection. But I'm wondering what does it take to over airate a tank.
She's in a 2ft tank filled to 40litres. There are two airstones, one in the corner filter and one buried under some rocks. Are two airstones too many?

I personally wouldnt say thats 2 many.. I used to have the same in my previous tank with no problems... just carry on salt bathing and see what happens

It takes a lot to over aerate a tank. You would REALLY have to be trying to do it, as excess oxygen just dissipates out of the water. Unless you can see very tiny airbubbles suspended in the water at all times, it's not over aerated.

Thankyou, I'll just keep up the salt baths.
