Prime is the best

Prime is the best dechlorinator on the market in my opinion. Aquarium Co-op has fast shipping, competitive prices, and excellent customer service!

Good Product

I’ve used this product every time I change or add water to my tank, my chlorine is always 0 when I test the water. I love to buy from the Co-Op because of their prompt shipping.

Great product

I have used several brands of conditioner and this has turned out to be my favorite.

Best water conditioner

I like Seachem Prime because it detoxes ammonia for your fish while still leaving it available to be broken down by your biological filtration. Best of both worlds!
