Chemi-Pure ELITE by Boyd Enterprises

Keeps water pretty clear and works well to rid the tank of unwanted by products. It is price, especially since you have to replace it about every 4 weeks. I have heard Chemipure Blue is better and more like Elite + Purigen so I will try that next. (Posted on 8/15/2018)

Known product, bit on expensive side, for carbon with added gfo .
Small convenient bags, easy to fit to any filter canister or HOB. Water clears up quickly and you can see it working right away.
Only question, will it hold up for 3-6 months as advertised or more in line 1-3 months? I'll be glad to get 3-4 months out of it to justify the price. However you should take into consideration your tank size, cleaning habits and stocking levels.
For 2-3 tanks it's good solution to eliminate frequent carbon changes more than that it will add-up cost wise.
Will recommend this product based on my experience, give it a try. (Posted on 6/9/2015)

Just purchased this product so I don't have a long experience however on first impression is the water smells better and the water is clearing up. Will know more as time passes but for now I am pleased with the results. (Posted on 3/4/2011)

I use this in my nano tank. It does what it claims to do. It keeps the water clean and takes out some of the smell from the water. Simple to use and doesn't cost much at all. A good product overall. (Posted on 8/4/2010)

Have been using regular Chemi Pure for several years. I love the product. It keeps water clear and keeps things looking healthy. I figured I would try this Chemi Pure Elite and see how it works. I was having a bit of an algae problem. I put this in my Magnavore Simplicity Reactor(Also purchased from aquacave.com and LOVE it), and it seems to work very well. I also have been leaving my refugium light on longer to give my cheato more light, so Im not sure what has helped knock the algae issue down, but this product is definitely works. I always recommend this to my friends that I know who use a lot of carbon. They all stick with the Chemi Pure once they try it. Aquacave has the best service Ive ever dealt with. I only buy from here, and am always pleased with their prices, products, and people. Thanks aquacave! (Posted on 5/19/2010)

Easy to place, helps keep water clear and non smelly, less algae
Great product, easy to use. Longevity based on the load of the tank. (Posted on 4/26/2009)
