It was used to clear a garden fish pond. As this takes time, i do not know if it works or not. Only time will tell.
Good prompt delivery and easy to use
No idea what sheerness means so cannot give an accurate score
Pond water very clear after just three days, but sediment blocking pump filters so need to clear daily. So far, so good, very pleased at the moment.
I have used this product ahead of clearing the bottom of a pond we acquired when we purchased a house. There is a significant quantity of leaf debris and the product of keeping fish at the bottom of the pond resulting in the pond pump filter and main filter becoming clogged on a regular basis.
After trying to remove the debris by hand, I decided to use this product initially to break down some of the solid material and I have left it for a couple of weeks to start the process. To be absolutely honest, we have acquired a large pond and to drain it an clean it properly would be a huge job.
The water appears clearer and my pump and filters require cleaning less often. I am though going to remove a substantial quantity of the debris shortly with my newly acquired pond vac and will then use this product periodically to break down any surplus food which might gather, leaf debris and fish waste.
Seems to work well and certainly removed some of the finer debris from my pond.
My fish were dying in big numbers earlier this year. This, along with the pond equaliser solved the issue. Will definitely use again but as a preventative this time 🙁 Just wish I had know what to do earlier. We inherited the pond when moving house.
I tried everything to keep my pump clear of sludge nothing worked till we treated with sludge clear.
Used this product may times before, however this order arrived crushed and the tablets were all broken. Will not stop me buying again.
Item as described. Fast delivery. Have used it but too early to assess it’s performance. Only time will tell.
Had a bad sludge build up in my filter and pond , the water was always murky . I used this as described and pond was crystal clear in a couple weeks . Great produc
After cleaning out our garden water feature Envil added that much needed strength to gazzump the dredges of sludge and bacteria. Easy to use and good value for money
My small pond was so dirty with decomposed organic material I honestly didn’t think this would work, but thought I’d try. It worked perfectly. Literally cleared the pond within three weeks. Amazing product, good price, would highly recommend. P.s. I had a small water pump which helps.
Applied one tablet, one week later pond completely clear. Can clearly see fish happily swimming around now. Brilliant product.
We have quite a large pond 6m x 3m and it look 4 weeks to get it cleared but it took a green soupy mess to a clear pond. Would use agai
Used IAW instructions and pond cleared within 3 days allowing me to again see me fish. Adding a second dose a week later has let me see the 4 babies they have had over the spring. Excellent produc
6 tablets in pack. Use 1 a week for pools under 5000 litres. To early to know if it works. But have added to pond fingers crossed!
I have tried many treatments over the years with varying degrees of success. This product has actually worked. It took time. You start with a double or triple dose and then at weekly intervals, a normal dose. Pond now clear. So fingers crossed it will remain so through the summer as hot weather and sunlight are key drivers for algae production.
I used this product a week ago in my large pond and it appears it is working regards joh
Easy to use product, jury is put whether its working yet.
They are awesome works in about 5 days but the pond is nice and clea
