Aquapapa Bulk Pack Economy Activated Charcoal Carbon for Aquarium Fish Tank Koi Reef Filter (10 lbs)

I recently purchased a canister filter for my 75 gallon aquarium and planned on using bio media and carbon as on additive for water stank and clarity.This is indeed, just a 5lb bag of extruded carbon. What's nice is that it comes in a big mesh bag, maybe for a sump? The quality seems good and it's definitely a smarter buy then the API activated carbon because, at the end of the day you can't really do much to enhance it beyond the fact that it is just a very pourous, oder removing, water clarifying chemical.A negative that I did have with this product is that it does have alot of dust that it will never rinse out to be 100% clear, but that's kinda to be expected because it is just carbon sticks rubbing together making more dust.Add this to a media bag and run it in a canister to clarify and deodorize your water or in a HOB with biofloss and you can start saving tons of money over filter cartridge replacements.

I placed it next to a pen so you know?what size?we are talking about. 5lbs of carbon for your filter below $20.... Works well with my 2 canister filters. Like this price and size a lot. Will buy again

I purchased this to use in a carbon reactor for our reef tank. I haven't noticed any negative effects so far after a few months but it is very very dirty and takes a very long time to rinse all of the dust out. Soaking it for a few hours first then rinsing seems to shorten the process but not by much. I'll be going back to the expensive stuff again after I use up all of it.

My 55 gal. fish tank had a milky water situation, the product arrived after 5p and I used it immediately, when I woke up the next morning, I was more than happy in 24 hrs it had cleared up by to my surprise 48 hrs I had crystal clear water!

I am using this in a potting soil mix and I love the larger coarse size to help with drainage. As another reviewer stated, it would be a good idea to crush these up for use in aquarium filters/ odor removal etc. More surface area and all of that. The price is unbeatable!!

They send me 5 LB in a plastic mining bag. Wish they had double bagged instead.I used this to place into cotton bags for passive smoke removal from air.I have been using activated charcoal bags from amazon, and assumed this would be a cheaper option.I did not return as it would be to messy, however i would not recommend this product for smoke removal.

So far so good. The volume you recieve is great. The only thing I will do when I change the next time I change my filter is to slightly crush the pieces, I think it cleans better.

I make my own filter element for an aquarium. This stuff is very very good. It keeps the water pure and clean without the high price for premade filter elements. My fishes thank you!
