Review: Amazing - We have well water with a high iron content. My wife has tried several products to no avail. I bought a pack of these. At first it changed the water to a purple color.(i didn't clean the tank as directed first). That lasted a few weeks. My wife was not happy. Then the water turned clear and all the iron stains etc. disappeared. I'm now a hero !! It states it lasts a few weeks, but we're on our second month and the toilet is still super clean and I can still see some of the product in the tank. Great stuff.
Review: These pellets keep your ceramic toilet bowls like new - A one of a kind product which does what it says. You won't need a sandstone. Have used these for a decade because they neutralize the iron and minerals in the water in the tank before the water is delivered into the toilet bowl. Be aware each 'pellet' is solid and apx. 2" x 1.5"; a few orders have arrived with cracked pellets, from various dealers, because they were not in sufficient protective delivery packaging. The manufacturer seals them tight but the issue is the light wt. bubble shipping bag. If you have well water you need these.

A one of a kind product which does what it says. You won't need a sandstone.

### ⭐⭐⭐⭐ Not a miracle worker, but good for maintenance
*by A***R on July 24, 2020*

Pros: - maintained my tank after it was cleaned - helped flush out rust & build-up I couldn't reach - washed away the toilet bowl stain I couldn't get rid of - good price - no smell Cons: - doesn't work on a super dirty tank (thick black slime appears) - visible in the water as it comes apart (not a big deal, but guests might wonder) - lasts a couple days, maybe a week
