Works brilliantly in my pond - clears in hours
I've used this a few times now since I built my pond. I first used it after I introduced some new koi into the pond who then proceeded to stir up the bottom. Having read various reviews I tried Crystalwater and was amazed just how quick it cleared the pond. Literally within a couple of hours I could see it clearing and by the next day it was "crystal clear".
I have since used it a couple of times after huge downpours of rain which seems to cloud the water. I think the rain is dirty these days!.
I put it in in the evening and by the next morning the pond is so clear I can see all the detail even right at the bottom which is 4 feet at the deepest. Great stuff.
The only downside I find is measuring it out. You have to use the inner cap which only holds 10ml and so for a modest pond you have to measure it out 20 times.. Why they cant put measurement lines inside the outer cap at 50ml, 75ml, 100ml, ...l, 200ml etc I have no idea, it would make things much easier and less messy.Read full review

Amazing product that does what it says!
This product actually works unbelievably well. I've used it over the years in an established pond and continue to buy it.
It does not harm aquatic life (fish, newts, frogs, tadpoles etc.) or plants.
For it to work effectively you do need a pond pump to cycle the water.
If you have a lot of blanket weed, then it will gradually break up and float to the top. You must skim this off the surface.
Top Tip: if you haven't got a fine net, stretch some ladies tights over a wire frame so that it's flat (can use old net frame) - skim the surface and dip the net in a bucket of water to clean off the debris.

No good for me
My pond was impossible to see into because the water was brown and murky. I read the description of this product and thought it would be worth trying.
Have now used all of it in 2 attempts, but the water is still murky.
Not really impressed with this product.Read full review
