Review on 🐟 Seachem Prime: Powerful Chemical Remover and Detoxifier for Fresh and Saltwater Aquariums by Marina Knutson

I received these 1 gallon containers sealed from Revain - the protective cap was intact. I have 6 aquariums and I love fish very much - I spend a lot of money on my hobby. I regularly take care of my fish and aquarium. I usually buy my best fish from freshwater fish supply stores - they didn't have them in stock so I took a chance and ordered them from AMAZON. I have a quarantine tank when introducing new fish to minimize the risks to my tanks. I ordered 2 of these 1 gallon containers. Within 3 hours of applying a small amount and mixing everything was dead in both of my tanks - Red Courser Snail, Pleco, Badis, Decorated Kori, Rainbow Fish etc. I am devastated. When I returned to the container, I noticed TWO things that weren't up to the norm. Anyone who uses PRIME knows it stinks to high heaven, like sulfur and eggs. This container had very little odor. Next. There was a black residue at the bottom of the container. I did not notice. I took it to a specialty store that I frequent and they've never seen anything like it. So is it a fake? May be. I'll have to contact Prime to see if they can investigate this further. Please be careful. Don't buy it from Revain's market. It took me a couple of weeks so maybe there was a delivery issue somewhere due to the heat? I hope this can prevent someone else from losing their entire tank like I did. Huge financial loss and heavy heart!
