Encompass All 2 Pack - 24 Ounce Premium Laboratory Grade Super Activated Carbon with Free Media Bag Inside Each Jar - AM Brand

Incredible. I really like using this carbon and have used it in my freshwater and reef applications. For the price and qty alone you really can't beat it. It has worked well in bags and a reactor and does not grind away easily. It also rinses nicely when replenishing, As a matter of fact, I almost felt it was a shame to toss after my first change as it still looked great and was keeping my water crystal clear. I used it for a month and will continue to push a bit further to see to what extent it lasts. I tested my findings with the white bucket test and my water was crystal clear. I've since changed my setup to try a waterfall effect over a baffle in my sump to test the ways in using the product and it seems to be working great in this fashion as well. Good item and will buy from again. (Setup = 75g reef display with 40g sump, and a 40g breeder display for freshwater goldfish, no sump, and use inside of my Aquaclear 70's)

This charcoal is good once in place, but I'm on the fence about buying it again because it takes so many rinses to get it ready for use. I had black sink water for quite a bit longer than the BRS brand. It's also coarse, which I don't mind, but peers in my fish world have complained. It does the job though, and personally, I prefer coarse, but I'm no expert in tanks. I just think it's easier to clean the counters after use. I used it after a chemical treatment and my tank looks crystal clear so it's definitely doing its job.

I hate scented cat litter. I can’t remember where I read to add carbon to plain litter, but I tried it and it works great. This really cuts down on odors and the cats don’t mind it. The only thing to consider is if your cats kick it out of the box and you step on it, it could stain.

Cleared up my tank quickly and great for the price. Should include 2 bags though. There's so much carbon in each one that you either need to use 2 socks/bags or you have to use it separately.

Appears to be good quality but I did not get the media bags that are supposed to be in each jar
