Customers like the quality of the pet supplies. They say it's a good quality product for a reasonable price. The container is sturdy, easy to open, and pours easily. The package is made of quality plastic. The product lasts about a month or two before needing to be changed. The original soil was still good and had not gone sour or bad. It's also a great natural deodorizer that does not turn into a fine black powdery mess.

Updated 6/8/20 - I'm no longer drinking the Chemi-pure Kool-aid; Affordable and reliable product
4 Stars
Updated 6/8/20 - I'm no longer drinking the Chemi-pure Kool-aid; Affordable and reliable product
Updated 6/8/20 - I've been meaning to go back and change my review on this for a long time. MarineLand Diamond Media Premium Activated Carbon, Blacks & Grays, 40-Ounce (PA0373) has officially gone back to being my go-to active carbon for my 160 gallon mixed reef. Ounce for ounce and ounce per dollar, short of buying in LARGE bulk from one of the dedicated online fish stores, this product has provided consistent results at the right price point. I'll take off one star for it being so dusty. It feels like I've wasted a lot of water rinsing this stuff before putting it in my tank.Per my earlier reviews, I do still occasionally find it lodged in impellers but you could reasonably argue the fact that the carbon is getting in my impellers is my fault.Since my original review, BRS has done some good videos outlining the pros and cons of the various styles of active-carbon. I'm not sure if it was BRS, but somebody also did an excellent video showing a series of tanks all being cleaned with the assorted "flavors/sizes" of carbon over a period of time. After becoming more educated on how and why active carbon works, I've tried the high end stuff, the bulk eBay pond stuff, the boutique stuff, and ultimately I always come back to the 40oz bottle of MarineLand Diamond Media Premium Activated Carbon.So, I apologize to the good people at MarineLand who make the product. It amazes me that I've been in this hobby for almost 20 years and I feel like I'm still constantly learning new things. Knowledge is power, folks. Learn on!~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~I decided to try this stuff instead of my usual product ChemiPure. I use a Phosban Reactor 550 for carbon filtration on my 125 gallon reef. A couple weeks after putting this new stuff in my reactor, I noticed that my reef octopus BH-2000 skimmer was making strange noises. I also noticed a lot of the new activated carbon floating on the surface of my tank. I discovered that the carbon was getting stuck in the finger impeller on the skimmer's pump. The image was taken 24 hours after cleaning the impeller.Also - I normally see a huge improvement in water quality 24 hours after using ChemiPure. I didn't see any improvements with this stuff.I've ordered a new batch of ChemiPure. The marineland product is going in the trash.
