It seems that Wiggles and Kibbles (my goldfish) are suffering from fin rot. Wiggles' tail is especially getting damaged. 
I'm having a hard time finding how to cure it. Most of the information I found said that it is usually caused by problems with water quality. I tested the water and aside from the pH being a bit high (around 7.8) and the water being a little bit hard (KH of 60mg/L and GH of 100mg/L) it seems fine (no nitrite or amonia).
I might try to get some aquarium salt and see if that helps. I really want to avoid using antibiotics except as a last resort.
Does anyone have experience with fin rot? Any suggestions for treatments?

He's always wedging himself under pieces of wood or under plants to keep himself from floating to the surface. It seems that he lost control of his floating. Whenever he's not wedged under something, he floats to the surface, all crooked until he manages to swim back to the bottom.
