Chemi Pure Elite Boyd Enterprises ABE16743 for Aquarium, 11.74-Ounce (2 Pack)

Ive used this for over 7 years in my reef tank and its amazing

Great product for polishing your aquarium water.Worth the pricy cost with little downsides (prep).My tanks get crystal clear and I use with a second media to enhance all around filtration.

Used this product for almost 2 years in my 80 gal, have 2 bags at a time and replace them every 3 months as directed. Never had a problem keeping parameters, nitrates, and phosphates in line!

Amazingly clear water

This is pretty much a required item for any aquarium filter. It helps keep the water clear and healthy for your fish. Ive used these for years and my fish are MANY years old. Too many people try to skimp on cleaning and filtering materials for their tanks and wonder why their fish keep dying. This is cruel and unusual punishment for them! Get in the routine of making monthly 20% or so water changes and keep the filters running clean. I replace these every couple months.

Laziness is a a virtue. I love the idea of not having to do thr same thing twice. Just change the old for the new, and it is done. Moneywise is probably e the same

Works great

The very best chemical filtration available - wouldnt set up a tank without it. Remember to rinse it quickly before using.

Top of the line product. Its very good for keeping your water clean and polished for the reef aquarium.

I bought these for controlling the algea in my 30 gal reef tank, it improve but not much may be the way I am using it, I put 2 pack in my back hang on filter , I am building sump now to combat with the algea problem, the fish and coral still ok
