Bulk Pack Economy Activated Charcoal Carbon Pellets for Aquarium Fish Tank Koi Reef Filter (20 lbs)

I use this in my Lomi composter. Love it. Buy bulk and save money.

Nice product, bulk package last longer. Nice size pellets & come with zipper filter bag. Good price

Tried granular charcoal, and found it to be a bit messy. Decided to try pellet form, will continue to use. Ease of cleanup compared to granular.

I used this product for a small outdoor pond and it worked well. There was not much carbon dust at all present, but I still pre-rinsed it prior to applying it to my pond. When used in a pond, the product should be placed in an area of high flow like the waterfall filter or the skimmer box.I've seen a few negative reviews left by people who said that it did nothing to clear up their green water. Of course it didn't. Carbon does NOT get rid of green water. Your green water is caused by phytoplankton blooms. Lowering nitrates, phosphates and dosing beneficial bacteria (which outcompetes phytoplankton) is how you get rid of green water.

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.

The pellets are good and at a decent price, I use a lot of them in the pond filter. The bulk price is about the same as I’ve paid locally but the bulk pack is hard to find.

This is a great deal on filter media. Just rinse it first.

Best carbon ever used
