Review: This stuff does what it says on the label! - This stuff is amazing! I used two other types and still got green algae etc in my water feature. Having read these reviews thought I'd give it a go, scrubbed my water feature, and have been using this as directed for one month and no green sludge or algae has appeared, it's fantastic and I'm pleased it's bird friendly etc.
Review: Hydra actually works - In previous years I've tried lots of different products to keep the water in my fountain clear. Invariably I ended up with discoloured or green coloured water in a short space of time. Now I can't believe it, Hydra actually works. It's only been a few weeks since I bought and installed but the water is crystal clear. I dare say it will discolor after a while but I've never had it so clear for this long before. I have already recommended this product to others. Very happy. 👍
