    Use this on my 75 gallon community tank and 125 gallon discus tank every time I do water changes. I dont have anything to test for chlorine but I use nothing but tap water and do partial changes as much as 50% and have not had any sick or dead fish so it must be working. I like thyat the dosage needed is very small so a bottle last a long time. Great value compared to others.

    I usually buy Prime from my LPS, but they were out of stock at the time. I really like this size for Prime since I have multiple 55+ tanks. While most other water conditioners treat 10g with one cap, Prime can treat 50g per cap. This saves me a lot of money, and Im also very satisfied with the overall quality of this product.

    I like the fat that only a small amount is need to treat water on water changes for your aquarium. It also suppose to detoxify ammonia in tank if you are having a problem with that.

    Seachem is a brand that achieves success by marketing to aquarists who think other brands are too cheap or too commercial. While their medicines and various other products are essentially bottled poison, their aquatic chemicals are a decent line of products, most notably, this one. However, for the average aquarist it’s a bit difficult to use, in ways that are borderline stupid.

    This was good and it did it’s job just fine. It’s just that it smelt very bad. It left the tank smelling horrible so it’s not that good.
