Outstanding product, it works perfectly and clears green water!
This product is truly amazing!!! Used in conjunction with the Hydra Pond Filter Blanket-1 sq metre in the filter system and it picked up and cleared my 10,000 litre pond. Before I could hardly see the fish and now I can see the bottom as clear as day.I have tried many other products and this is the only one that works!

Excellent prod
I would highly recommend this product. My Koi pond water is practically crystal clear after one treatment. I did the glass test recommended by the manufacturer and you can see the remarkable results. I took two glasses of pond water and treated one and left them overnight. The treated water was almost as clear as tap water.

expensive but the best tried so far
Very good to clear water. Then comes the work clearing the dead stuff. Well worth trying, but if your pond was dirty like mine then the work begins. But it does the job very well

It does do what it says and quickly, but.!!!My pond is 558 gals. It has never turned green before in 10 years. I used Crystal in a careful measured dose. It went clear over night. The next day it was fully back. I tried again with the same results. Now I overdosed putting in more than double (all I had) the surface was in a mess with scum but the water was clear. Three days later it is green again. I have non left. After a week it has gone to an inky green unable to see more than three inches below the surface. I am now at a loss

10/10
10 out of 10! Was delivered on the 28th April, put it in the pond on the 28th and started to clear within a matter of hours. As of today (14th of may) the pond is still clear. Will be buying again if/when needed.

the product helped tremendously but didn't quite clear it completely but has been in the water over the winter and it is amazing
Had a huge problem with green gunk towards the end of summer 2014 when I purchased this product, the product helped tremendously but didn't quite clear it completely but has been in the water over the winter and it is amazing! The pool has gone crystal clear and I am confident that by having this product to start the year we will have a nice clear pool during 2015.
