Premium Activated Carbon for Aquariums - MarineLand Diamond Media, 40-Ounce (PA0373) Review

I was trying to get my tank rid of this yellow discoloration. I did a 50% water change and it's still very yellow. I have set my skimmer to yellow every day so far. I ended up buying a Purigen and this charcoal and it cleared up within an hour. I poured it out of an old small canister filter. Purigen was there 1 day before I put everything in the canister. Cleaned up in an hour. Wonder. It's dissolved organics that could repair them. Getting it through the reactor really makes a difference…

Got stainless steel exhaust filter for 3x3 grow tent. Remove the filters, three screws at the top and bottom, and remove the old activated carbon (the product has the same activated carbon size as the old activated carbon in the filter). Filter with new carbon, put in a mesh bag, screw back in and WALLA. Completely new! I think this charcoal worked better than the filter that was originally included! ABSOLUTELY ZERO ODOR and has been going strong for over a month when my plant flowers. Don't…

We ran out about 3 years after putting it in the litter box. We didn't buy it right away. We soon noticed. smells. No matter how many times we cleaned them, the trays just stink around them. I decided to buy another pot of this. Sprinkle a little on the trays and all odors will be gone within a day. You can literally put your face close to the hole and feel nothing. That's great. You don't need much, it should be like 5% charcoal 95% junk. Cats don't notice and don't mind if you keep the…

I purchased this activated charcoal (or charcoal) in July 2015 and have only used a cup or so over a year later. A 40 ounce container will serve us forever. It can be used for aquarium and water filtration, odor removal, skin care masks and more. I bought it for teeth whitening (google activated charcoal for teeth whitening if interested). It's very messy in terms of white shell stains or whatever if you're not careful. A coffee grinder or food processor will help with grinding (since you will…

I bought this to add to kitty litter as other reviewers recommended using it for odor absorption. In fact, I believe it absorbs odors and I don't even have to mix too much for it to work. Note, however, that this makes things a bit black and dirty because the cats are chasing him outside the box, along with all the debris stuck to their paws. The white tiles in the bathroom need special care and my white footed kitty now has slightly black charcoal paws (my other cat is black so I can't see his

Before you put this in your fish tank, take a strong magnet and pass it over this charcoal. Carbon is not magnetic at all and nothing should stick to a magnet. If this is the case then the iron and possibly other metals are mixed in with the carbon you purchased and this could be having a negative impact on your reef aquarium. I got this for my reef tank. I had to rinse the charcoal for quite a long time to get rid of the dust and I put them in 2 brand new mesh bags and put them in 2 of my 4…
