Envii Pond Klear & Sludge Klear – Improves Pond Water Clarity and Reduces Sludge Down To 4°C

This is without any doubt the best pond project I have ever bought in my 12 years of having fish in garden my pond was filthy could not see 2 inches down now I can see the bottom and my fish seems happy and very active I can’t say enough about your product will always use it thanks from Brian Hardy.

works well... not straight away.. you need several large treatments then reduce... but have used for the 1st time this year and although slow to work.. it has now maintained a good level.... and with this product you can used though winter... so see how that works out for me...I don't have filter or pump, just a natural pond with assorted plants.. and always a bunch of watercress.. and I find all this works... fish and frogs a very happy.... hope this helps.... :-)

My small pond came out of winter hibernation with a smell that could put any sewer treatment plant to shame. I was going to get rid of it (after seeing how much expense and hassle a pond pump and UV filter would cost me) when I came across this product. And it does indeed does what it says. Within a week a I could actually see the bottom of the pond (where I spied the wreckage of an old dead pump). And no more smells either.

Your sheet with additional info was extremely useful, thanks. I didn't realize how much sludge had built up. I now know my pump & filter very well. The water is still green but appears to be clearing slowly but you advised that this could happen.

Easy to use but didn't work for me.

Really good stuff. Keeps my pond clear and sludge free despite it being in a very sunny position.Brilliant stuff and no harm to fish or plants.

6 treatments over the course of 6 weeks: double dose, single dose, double dose, double dose, triple dose, triple dose. Tested ph first as instructed: perfect. Pump filters cleaned every 2-3 days as instructed. Hundreds of pounds spent. Result: no improvement, nothing nada zilch. Water not the tiniest bit less green and opaque. Complete waste of money and time. Do not buy.

Dosed the pond as per instructions it took a while to work but it did the job!
