Boyd Chemi‑Pure Blue 11 oz Aquarium Filtration Media Premium Extruded Carbon + Ion‑Exchange Resins in Nylon Bag Clears Toxins, Phosphates & Metals

Good product and does what expected but the price is higher.

Doesn’t work properly if u dont load 1 trey in the canister with this only. Unnecessary purchase for indian condition n pocket too

Fa cosa dice. Ottimo prodotto

Regular user of chemi pure blue. Fits well in the external filter basket. Within a few hours a difference is noted. By the next day the water is crystal clear. Removes any tannings etc and water smells good. Fish always seem happier after a fresh bag inserted. It is said to use bleach to restore the bag and use again etc. I tried it once, didn’t like the idea of putting it back in even once rinsed. So I bought another chemo pure blue. Rather a few quid here and there than poison my tank. Chemo pure for the win!

Excellent produit et très efficace, merci

Great product and great price!

Makes the aquarium water crystal clear and helps with smell. I'll be buying again in the future. Once of the simplest thing you can add that has drastic improvement to water quality. The size is large and easy to place.
