RezBlock- All Natural Resin Blocking Water Pipe Additive 8oz

This is a product definitely worth checking out. Sometimes extra build up at the bottom sticks heavily to the glass after sitting too long, which is why you are reading this review, but with this product the chunks remain broken up and floating in the water. For best results with this, try replacing water every 4-5 days instead of a week. The reviews about the water color kind of had me having mixed feelings, but you use such a small amount that the water only has a slight green tint. So for keeping glass I love clean and in great shape, the color tint is worth the trade. Hope that helps

I bought this item hoping to keep things a little cleaner in between deep cleanings. I used it for a few days and still couldn't get over the green cool-aide type water. I couldn't do it. It may be perfectly safe and even work as described but with color alone i cant use it. paranoid? of course i am look what i'm reviewing is used for. Anyways if colored water that is a bit thicker then normal water doesn't bother you then i'd say go for it. but if your like me then just stay away and just clean the old fashion way.

5 stars for functionality but in a clean bong i would rather get the red one because this nasty green color just doesn't look good in clean glass. But works great red or green all you need is a rinse

As an avid smot poker, I was skeptical about this organic product. I use a Medicalli water pipe has a tube on top, followed by an ice catcher, followed by a tree percolator, then beaker'd at the bottom. This makes the percolator very difficult to clean and maintain. Surprisingly, this stuff keeps the whole thing rez-free. It is a little inconvenient to have to change the water every week and refrigerate the product. Also, the deep green color is kinda an eye sore.

This stuff does that which I was hoping it to do. It might be stoner paranoia, but I thought I could taste it. Possibly a citrus flavor. I think more research is needed!

This stuff really does work. Although it does slightly alter the taste it's not in a bad way. I have a 5150 double chamber and wherever this stuff touches no resin builds up. Although not perfect because resin does not always build up where the water/rez-block touch it still works to prevent buildup and with regular maintenance really keeps things clean and functional

Awesome stuff. Super concentrated; you only need a few drops added to water. I can't taste any difference. I use GRUNGE OFF for cleaning (highly recommend! no scrubbing; just let it soak and then rinse) and REZ BLOCK for preventative maintenance.

good product. works as described.
