Joe Carr –
I’ve used Prime® in both my freshwater and saltwater tanks. It effectively removes chlorine and chloramine, and I noticed a significant drop in ammonia spikes during cycling. The water stays stable and the fish show no signs of stress. Highly recommended for new aquarists.
Tim North –
After switching from a cheaper dechlorinator, I saw better water quality and fewer fish health issues. The product works fast and doesn’t change pH. It’s especially useful during tank setup when ammonia levels are high.

Prime® performs well in my marine tank. It handles chloramine effectively and helps reduce nitrite toxicity. I mix it with water in small amounts and it’s easy to use. A little goes a long way due to its high concentration.
