Diamond Blend Zeolite & Carbon Filter Media, 50 oz | Removes Toxic Ammonia & Impurities For Crystal Clear Water In Freshwater Aquariums & Ponds, Keeps Water Clean & Fish-Safe

Great product and price. Fast shipping. Good seller, will use again.

I love this product for what I'm using it for. I read other reviews and noticed people complaining about the dust, I'm using them outside and the dust didn't bother me. I used some extra fine mesh bags and used them with my solar water fountains to help clear up my outdoor ponds. The water is surprisingly clear. The pond with the toilet has been clear since the day I put it up and had stayed that way after numerous rains and days with sunshine. Some days it does get algae but I noticed it usually doesn't stay long. I do have fancy water quality kits so I can't tell you how it does with nitrate reduction and all that fancy stuff. The bathtub pond had a baby rabbit in it that I had failed to rescue in time and it was quite..gross. the water was murky and green. Due to the size of the tub I was unable to empty it. I set up a "filter" with this product and I am truly amazed at how clear the water has become. I will definitely be using this again next summer.

This really does a great job removing ammonia from my fish tank. I’ve been using it for years, and it never disappoints

Works as expected

Just the right combination that keeps the tank clean and fishies happy. The ammonia level is always low and the water always looks crystal clear. This stuff last forever and carbon content is just right.

I love using this stuff. The carbon and zeolite work well together. Keeps the water very clean. I replace it every time I clean the canister filter. Will continue to use this item as long as I have fish tanks.

Pros: With following the rule of 30g to 30gal(min) this stuff works wonders, I had and was using HBH and it's carbon if excellent no lie but its Ammonia Neutralizing blend really was a waste. You may pay a tad more for this but that 3 bucks is worth every extra penny, plus EntirelyPets has it cheaper then the pet stores. Don't get me wrong you still smell a tad of fishy/turtle water but you gotta stick you nose in the water. -No smell compared to all other blends anyone with turtles will know that nasty smell this is you answer) -Lasts over a month *I change every month for best results* -Less dust then all others so you barely have to rinse it -If you water smells put this in a bag run you filter 24hr and your water will be crystal and smell free -Not saying you wanta but when you change the media smell the water then the media and you be like WOW this blend locks in a lot a smell and the only smell is off the media. Cons: -The picture is a tad wrong just like burger king their menu looks better then the food but the split on carbon to Ammonia blend is like 5 parts Ammonia to 3 parts carbon, but still works just stating any negative which isn't because its Marineland. Only other negative I bought two of these and one the lids were brittle and upon deliver it broke but box was taped up very good and I saved all it and still works*I know this isn't ship review but those are the only two negatives I have to say so buy some!!*

Excellent product, works very well. I used it as aquarium filter media--placing it in THE MIDDLE OF an Aquatic Experts Aquarium Filter Floss for Fish Tank Filters - FilterFirst Aquarium Filter Pad - Media Roll for Crystal Clear Water THEN PUT THEM IN Aquarium Filter Media Bags with Zipper for Activated Carbon, Biospheres, Ceramic Rings. WATER IS SO CLEAR OVERNIGHT!

The bottle have a crack hole

Ni hace falta lavarlo tanto y funciona de maravilla! No dudes en adquirirlo, créeme

Buen producto, mantiene limpio mi acusrio

Buen precio y calidad

Lo uso en mi filtro de canasta para mi tanque de tortugas y me ha resultado muy bueno, mantiene el agua cristalina. Cabe mencionar que antes de usarlo hay que lavarlo muy bien ya que si lo usas directo del bote el polvo que tiene ensucia mucho el agua y tendrás que cambiarla toda.
