Boyd Chemi‑Pure Blue 44 oz Grande Aquarium Filtration Media Premium Carbon + Ion‑Exchange Resins in Nylon Bag Clears Toxins, Phosphates & Metals

I use this product on a regular rotation in my 120 gallon reef aquarium. In combination with other filtration products, this will assist in keeping your perimeters stable and tank crystal clear & beautiful as ever.

Works perfectly. Have been using the products for 30 years.

I've been using it over 25 years in many saltwater tanks my main tank is 215 running in my filter you see the water change after an hour. I noticed how much more hungry my fish are plus more relax. You'll also notice how super clear the water gets.

This product is Simply Amazing at keeping tank water more clear. I have a 110 gallon African cichlid tank. I run this in one of my canisters and you can absolutely tell the difference.

I had never used Chemi pure before and had some extra change and it was at a good price so I had heard some good things about it and gave it a try on my 125 gallon fish tank and within 2 weeks of use I definitely could tell the difference less maintenance all across the board major improvements.

Works well crystal clear water

A must have for fish keepers.

Ok,so I have read all the reviews and YouTube videos on this item however I can't tell if it's worth the $ 80.00. I have about 400 gallons total water volume so it's probably a stretch to see any difference with my purchase of just one container,however I plan each pay period to add another unit to my sump to truly see if it helps. I can say that my living room area smelled like SeaWorld with all of the saltwater and feeding clams,shrimp,etc to reef tank,I did notice that after adding just the one package of ChemiPure I did lose the SeaWorld smell overnight....so that's great ! My water was always clear ...so I am still going to add more as my budget allows..

After dealing with cloudy water in my aquarium and trying what feels like every possible thing I could. I decided to order chemi pure blue in. This is before and after pictures!! Absolutely blew my mind with how great this stuff really works! I would highly recommend this product to any aquarist!!

I had a good idea of how well this would perform, but actually putting it in my tank has surpassed my expectations. This cleared my tank up overnight even with me already overfiltering my tank. I forgot how good my tank can actually look. Great product and will be buying again.
