This stuff really, really WORKS!
Recently changed aquarium to a cichlid community and am amazed at how well and quickly adding this media to my cannister filter CLEARED THE WATER! It went from a constant yellow color (even with regular water changes) to crystal clear in just a day. Fish seem very happy. Highly recommend!

Bought because of Kaveman Aquatics
This is an outstanding product that has significantly impacted the clarity of the water. Itâs also a great value since the cost is low and one unit lasts for months. Easy to use, just rinse and throw the bag it is packed in into the filter. Absolutely recommend, and as the YouTube channel Kaveman Aquatics says, this is a big reason why my water looks good.

THIS + SEACHEM PURIGEN!
If you want crystal clear water you definitely need to add in chemical media to your filtration! I run a Fluval FX4 canister on my 75G South American Cichlid tank and my water looks super clear (as seen by the photos). Compared to Seachem Purigen, CPB (Chemi-pure Blue) is a more all-in-one chemical media package. CPB removes Phosphates, stabilizes ph, supposedly also increases fish appetite? I haven’t really noticed this but that will depend on their diet and how much they enjoy what you feed them and ingredients. And finally it makes the water crystal clear! I added in Purigen just to help out as I do have driftwood in my tank and it’s really just that extra hand to help keep the water clean for a while until it’s time to swap out the chemical media. I will rate value a 4/5 as it can be a bit pricey but the results are still incredible.So good that even my biggest Electric Blue Acara named Bolt (right next to me holding the product) approves! as well as all the others!

Seems to be working well
This was recommended to me by a local store but they did not have this particular chemi-pure so I purchased it here for less that what it would have been there. It comes in a bag already and is ready to rinse and add which is awesome as I do not have buy a mesh bag or measure. My nitrates went a bit crazy for some reason and I needed to get it back under control so I did the other steps needed and bought this. It says it will last 4 months and if it does then that will be a great thing. My water is good now though I cannot be truly sure how much of that is due to this because I also cleaned and upgraded tank size. But I am sure that this has helped out. I will be buying another for my reef as this seems to be helping in my swim tank. I hope that it continues to be helpful and I can rely on it as then I will use it every few months as instructed cutting down on the guesswork. I would recommend this product.

AMAZING PRODUCT
So I’m new to the saltwater aquarium hobby, and am very picky about ultimately, the way I’d like my tank to look. To me the most important thing is having crystal clear water for the fish, invertebrates, and coral that will be living in the tank.So for the first week, for whatever reason, my water was extremely cloudy. So I did some research on the best product for excellent water quality and found Chemi-Pure. Honestly…the BEST decision I could’ve made. I took out the charcoal that was in the bottom chamber of my filter media already. I took the polyfilter that was in my top chamber and put it in the bottom chamber that housed the charcoal, and I put the Chemi-Pure in the top chamber so the water runs through it first. WOWWW!!!! A day later and my water is crystal clear!!!! No cloudiness, no nastiness, only extremely clear water. Happy fish, happy coral, happy owner. Do yourself a favor and purchase this if you’re having any water quality issues. You WON’T be disappointed!!!!

Been running in my tank since August, and I swear by the stuff, works great! Running the entire jar in a Fluval FX6 in a 125g Freshwater Tank. Water is still super clear, and no algae, other then the little bits on the glass…but thats to be expected.

Water crystal clear at first use. My problem is to eliminate phosphates and Silica. I purchase1Chemi- pure Blue after I purchase 2 Chemi- pure Blue. I liked the product, my phosphates and Silica are reducing slowly. Highly recommended.
