I picked this up today and weighed it. It is 0.98 kg and not 1 kg as stated. The lid was not tight and contents were to the level as pictured. I suspect someone siphoned some away.

Recently purchased this product for my Fluval FX4 to reduce my ammonia level in my 55 gal. aquarium with Ammonia level at 1.0 ppm. Followed directions even adding a little more. Did 3 20% water changes during one week no change. Removed and installed Fluval FX Ammonia pad, 3 days later ammonia read 0.25 ppm. Will never buy this again !

I purchase this to eliminate any ammonia in the fish tank as fish gives this off when they 'pee' and charcoal does not do the job.

Use these for my pon mix for plants. Great price. Perfect size. Crystals are in great condition. Don’t tell the plant community about it cause they’re mine

Works so well I’m thinking about lining my infant son’s diaper with some. I may have to think twice about that though.

I have spent months trying to get my pH under control. I finally came upon a stream of comments on one of my aquarium youtube channels that recommended to try zeolite to diminish ammonia. It works.

It’s a little tough to open and then it’s rocks but it floats and overflowed

I bought this a month ago and I’m so happy I did ll
