K. Nasr: Never seen my 20 gallon aquarium, with 5 gold fish in it, crystal clean water until I started using this product. I add 4 tablespoons in a mesh filter bag and put it inside my homemade submersible filter.
WARNING: You must rinse very well before use. Rinse until dark colored water becomes clear

Mrr2023: I was getting tired of PrettyLitter cat litter smelling like urine after a couple of weeks. The only solution would be to replace it, which ends up costing a lot. I even have a hepa filter running next to the litter box and still the ammonia smell is persistent. I decided to give this aquarium blend a try, and happy to say that it works. I stir up the litter 1x per day and even a month later, the same crystals don't stink. I only add half a cup to the litter box and that seems to do the trick.

AronAron: I used this for almost 4 years for my 80gal tank. To make my own filter stuff. Works good easy to use. Washes very well and not much colour run off. Helps keep water clear and clean for sure. Good value for money at the time I bought it. The dual mix with carbon is nice so I don’t have to have two containers and mix together. Not that mixing is hard but is convenient.

JasmineJasmine: I had bought a gravel vacuum with no suction pump so it's really difficult to use and my tank had been a mess for a couple of weeks... Filters for this tank are hard to come by so I used this zeolite (with a bit more carbon) in a mesh bag and put it into the filter with some fluval foam and ceramic (aquarium) rings. All I have to do is poke the bottom of tank to move around the build up because my filter is so weak. I changed around 50% of the water at midnight and it was very clear by 9am - still looks crystal clear days later.

CountryGal: This is a good product & I like the convenience it offers, being preblended. That said, after ordering it & using it, I realized...it doesn't last that long and I could save money by purchasing these products separately and blending them myself. Product arrived as expected & have no complaints with Marineland. I have many products made by this company & have been pleased, overall. It's a good product for convenience, but keeping fish is a costly hobby, so I take try to use the most cost effective means possible. I gave it a 4 based because it does what it's supposed to do, is convenient & priced well, in comparison to similar items, but for practicality, sorry. You pay for convenience, folks! Last, I didn't appreciate that it's not well sealed. That impacts the potence and longevity of a product & impacts my level of confidence in the safety of the product. Like anything else, it should be well sealed upon completion of packaging. Use your own discretion.

Placeholder: Here is my experience with this product. Today is my 5th day using this product, and Wow!!!!!!!!! my 5 gallon fish tank has only 3 small fish an I only feed them once in the morning and once at night. I feed my fish tetra flakes. Every 3 days my tank was so dirty/mucky and stinky. You could smell a fishy fowl Oder 15 feet away from the tank,so I had to wash the whole aquarium top to bottom. I ordered (Marineland PA0392 Diamond Blend ) from Amazon for an awesome price. My tank was very dirty and stinky when I filled a thin baby sock with about 5-table spoons of this product , tied it with a trash-bag twisty then placed it into my filter (API SuperClean Power Filter, Size 5 to 20 ). My tank got extremely cloudy, making it impossible to see though it. then in an hour or two I noticed upper half of my aquarium started looking clear. By the next morning the whole tank was crystal clear and the bad Oder was about all gone. by the third day my tank had no bad smell and the milky powder stuff that was everywhere in my aquarium water fell to the bottom. By the 5th day 100% clean smell and absolutely no filth in my aquarium water. Amazing!!!!!!!!!!!!!! I recommend everyone try this product.

Z. S. Proctor: 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...
