fins disapearing????

liquid tests i got them at the local pet store but i'm out of everything but p.h tester and ammonia tester so i've just been taking a bottle to the lfs and having them test and she said that everything was in order she evan double tested my p.h. and ammonia for me.
 
I only trust my own test kit..

I would suggest you get your own test kit and test the water.

agression and water quality are about the only real contributing factors when fins are damaged.
 
well lost another one, tested water everyother day (finaly got more tests everything was fine), did extra 20% water changes every 4 or 5 day instead of every two weeks. so all that i can come up with is aggression?
