Slime disease on my tetras!

Yellow is the tannins from the leaves. Tannins don't normally change the pH unless you have lots of them in really soft water. But a few leaves won't change the pH.

Yes I know about the tannins. My water has a GH of 3 and a KH of 1. So it is quite soft. I'll try with some peat moss then.

If you continually do large water changes your pH also won't move.

I don't continually do large water changes. I do 30% weekly.
