Boyd Enterprises Chemi-Pure Blue Filtration Media for Aquarium, 11-Ounce (2 Pack)

Just add to your filter chemical media tray! I run this and seachem purgen and haven’t had any water issues. Clarity is top notch!

A must have for fish keepers.

great product

Did not raise ph in my aquarium. Will stick to GFO and carbon they are cheaper and do just as well

Forget stock media, and stock carbon! This stuff will house beneficial bacteria, give you crystal clear water, remove phosphates, and Nitrates! Works and fits perfectly on a hang on the back filter, canister filter, or a high flow area in your sump! Easy to use! Just rinse the bag under water to rinse the carbon, and place it straight into the filter of your choice!

Great in my Canister!! Clears water fast!! I love it!!!

Good product

I have been using Chemi Pure blue for some time in my 100 gallon saltwater tank and never had a problem with it and have been very happy with the product. My most recent order I opened the containers and noticed it smelled like fish, I didnt think anything at the time. I rinsed before putting in my filters. The next day my tank was cloudy!! I did a quick water check and my nitrates were through the roof!! I had a severe bacterial bloom. I pulled both chemi pure pouches out of my filter and threw them in the trash. The bloom lasted 24 hours, Unfortunately I lost my beloved flame Angel and Fairy Wrasse. All of my other fish survived. I since have ordered more chemi pure and they smell like nothing when I open the containers. Do not use if when you open the container it smells like fish!! You may throw off your entire tank and potentially deal with fish loss.

A must have for reef aquarists. Slows down algae. I have tried others. But this seems to be the best

Works great!
