How often should I put Tetra dechlorinator into my 2.2 gallon fish tank with three guppies in it? I know the amount, I just need the best time in between please. Thank you!
Trying to treat betta for Popeye otherwise healthy happy and active. Moved from five to three gallon filtered heated tanks. Feed freeze dried blood worms, daphnia and bug bites by fluval. Also am changing some if not all water every few days. Treated with kanaplex several doses no real improvement. Switzed to metroplex in water treatment as I don't know how food treatment works or how to dose started four doses two days apart and there is some improvement to the eyes. Med is miconidazole.

So since the last time I asked he started to show signs of fin rot and this morning I saw one thin white filament attached to his left fin. Doesn't appear to be attached to his body anywhere else but his one fin. He is in a 1 gal tank and I put a fungal treatment in his bowl. Was this the right way to go or should I simply keep with salt and pristine water
