Ive treated my tank with prazipro for 2 weeks now I'm sure it's flukes and I don't use activated carbon I use Fluval Clearmax is it ok to use or should I remove it and just run filter sponges and ammonia remover bags and Fluval bio max and Ive already treated for 2 weeks and they're still flashing or is it because my Ammonia is still at 0.25 ppm ?
