Hi Heather,
I also don't like CopperSafe or Maracyde or Super Ick Cure. Because it almost kill my breeders on my first shipment treating them prophylactically with those meds and I swear it, it will never ever have a chance for those meds to be stocked in my fish room ever. Well for me as a rule of thumb you should always have IAL, Banana leaves and a lot of Rock Salt. I just wanted to add up Aquarisol (Copper Salt) to my water because generally it will prevent clamp fin, fin rot etc... but I will cut the concentration in half on preparing it just to make it a preventative addition to my water.
NOTE: I did an experimental test on my cull bettas 6 of them, I did this test because I wanted to know whats causing me to have dropsy because I lost one of my favorite betta fish on dropsy. So I finally pin point whats causing it one of my live food grindal worm so I did chuck all my grindal culture and won't be using any of it in the future.
Happy Betta Breeding

Cheers,
Francis
