Crystal Water works best alongside routine aquarium maintenance.

"I had Malaysian trumpet snails take over my 125 gallon tank years ago. Through pure chance I found this product while browsing through the site and thought why not? In 3 days the snails are gone. I am so excited to do a rescape now that those pesky snails aren’t around making the tank look bad! Definitely recommend! Oh yea, I have fish including scales fish as well as neocaridina shrimp and they are all still a living and appear to be doing well."
