When you add RezBlock concentrate to your water, it prevents resins from sticking to the glass and instead they float in the water allowing you to pour out that gunk along with the ash and other particulates you don’t want. RezBlock is completely organic, which means you do still need to change your water out regularly. With RezBlock and regular water changes, you’ll see drastically less buildup in your glass pieces.
- Contains fruit extracts, vegetable glycerin, purified water and citric acid
- Doesn’t affect the taste
- Just a few drops needed with every water change
