I want to add that It has been 3 days since I finished treatment with Metro and added the Driftwood.
What I am thinking right now is the following Add salt to the aquarium between 0.01 to 0.2 % salt as recommended by the salt article here at simply discus.
And in case its ich I can combine that with temperature swing technique (raise 90F for 24 H then lower to 70F for 48 H and repeat 3 times).
As two least intrusive treatments. As I don't want to go through a medication treatment again unless necessary.
I need advice from someone more experienced, because if this is caused from a bacterial infection increasing the temp will make it worse. and I will have to treat it with Terramycine as I read that identical symptoms were treated with it.
