CHEMIPURE Filtration Media for Aquarium, 11-Ounce, Blue,325 ml (Pack of 1)

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!

This stuff works,it will arrive wet this is normal,use as directed and you won’t have any issues,I use this in a media reactor with good flow and works for me,now delivery it says when you buy the 45oz it usually takes 2 to 3 days after you order it this jumps to 2 to 3 weeks I found this un acceptable and feel as l was lied to no contact or anything won’t be buying from this company again.

I don`t usually write reviews but I just had to shout loud about this product. I have tried many different products to help with Phosphates and Nitrates in my 100ltr marine tank and non have proved very effective but this little baby is terrific. In just 3 days my tank glass now stays clear, my water is now stable regarding both Phosphates and Nitrates, so at last I have found a product that does what it claims it does, I shall be using this from now on and another good things is that it only needs to be replaced very 6 months.

I have to edit this review as I have seen other comments on this saying “it’s been used, it arrived wet” it is supposed to be wet, this is how it comes 🙈 and others saying it made my tank cloudy, read the instructions first, rinse it in cold water first until the water runs clear. I’ve been using ChemiPure blue ages, as you can see in my Fancy goldfish tank, who are by far the messiest fish, it is super clear. Quick delivery, I use this stuff for my fancy Goldfish 200 litres aquarium, they are messy and produce a lot of waste, this stuff clears the water in a few hours and doesn’t need changed as quick as activated carbon or Purigen, it’s a little expensive for what it is, I’d give it 4 stars overall, a very good product, but a couple of quid overpriced in my own opinion.

I've tried other products with no real improvement, thought I'd give this a try, omg what a difference, 2 months now and my water is crystal clear, It's a miracle cure definitely recommended 👌

Didn't quite believe other reviews but my South American Cichlid tank cleared very quickly,have 2 Fluval 407 running on 125 gallon tank, product in top container in just one of canister filters.

Is working well. It is in a external cannister filter and has stabilized my 90 gal (imp) mixed 2 1/2 year marine tank. This is my third consecutive purchase and will be using it permanently.

Wow just wow. Had problems with diatoms and nitrate levels before I put this product in my canister filter. Nitrates dropped and diatoms basically disappeared within 24 hours. Have tried different water conditioners but this one is superb Buy Buy Buy

Fa cosa dice. Ottimo prodotto

I have been using this product in my biocube 14 for a little over a year now and it has worked great for me. I have this placed in the second compartment in my biocube 14 filter. I don't have a media basket or anything. I use this along with live rock, purigen, and some filter floss in the second compartment of my biocube. I replace it every 5 months or so. I have to say I am not 100% sure that this is the reason for the success of my little biocube, but I have to admit that my tank stays very clean. I have not had too many algae outbreaks. This product contains activated carbon and gfo. The activated carbon helps remove the toxins from the aquarium while the gfo helps to remove any phosphates that may promote algae growth. One of the main issues that I have with this product is that it takes a while to rinse out and clean the carbon initially. It never completely washes out while rinsing in tap water. I usually only wash it for a minuet or two and then place it in my tank. Once placed in the tank however, it does not leach any carbon or anything that I can see. Overall, great product Pros: -small size, great for a nano tank -low cost Cons: -takes a while to rinse out.

I run a heavily stocked 220-gallon aquarium housing 17 large clown loaches, a Jardini arowana, and a Black Diamond stingray—so maintaining top-tier water quality is critical. For filtration, I use three Fluval FX6 canisters, with two of them loaded with Chemipure Elite Grande. I clean one canister each month (each individual canister gets serviced every 3 months), and I replace the Chemipure in whichever canister I clean that month. Results? Outstanding. Water clarity is crystal clear, even with a high bioload. pH stays rock-solid stable, which is vital for sensitive species like loaches and rays. My fish have shown increased activity, improved coloration, and better appetite—especially the stingray, which has become more interactive and alert. Algae is nearly nonexistent, and I no longer deal with phosphate or silicate issues. No more strange odors, cloudiness, or worry about heavy metals, organics, or phenols. I've experienced significantly reduced fish loss, thanks to the consistent water chemistry and the elimination of osmotic shock. The product says it lasts up to 4 months, but my rotation every 3 months aligns perfectly and ensures optimal performance. If you’re serious about the health of your aquatic pets—especially sensitive and high-value species like stingrays—Chemipure Elite Grande is a no-brainer. It supports a thriving ecosystem and takes the guesswork out of chemical filtration. I won’t run a tank without it.

Excellent produit et très efficace, merci
