Used Maracyn Two for a fish with dropsy and saw improvement within a week. The powder dissolved well in the tank water and the fish showed signs of recovery after a full treatment cycle.

Helped treat a case of popeye in my community tank. The fish responded positively after following the dosage instructions. Easy to mix and effective for bacterial issues.

Tried it for fin rot in a saltwater setup. The treatment worked well and the fish healed without further complications. Good product for bacterial infections in both water types.
