This product was purchased to treat a betta with Saprolegnia fungus based on recommendations I found online. Before I put the first dose of PolyGuard in the water the fish were doing better, eating well and being very active in the tank. I have used many Seachem products in the past and have always been pleased with the results. Even though I followed the instructions exactly 6 hours later my fish was dead. I feel terrible about it. Based on my experience with other Seachem products, I assumed this product was safe. I put it in the aquarium, went to bed and left the fish unattended. I will be returning the unused part for a refund and will not use this product again.
