Great product.
We have had some green water and blanket weed problems this year and also due to an accident were unable to use the pond vac we normally use so I bought this product to help us and I am very pleased with the result so far. I also used Cloverleaf Blanket Weed remover - but on different days - and then put the tablet into the pond water as described on the packet. We are now nearly back to clear water and the bottom of the pond is looking so much better. It is good value for money too as our pond is 4000 litres so I only need one tablet each week. I will be using this next year from spring onwards to keep everything looking good.

All tablets were crushed
Had to return them as neither packet had a complete tablet and so difficult for dosage. No protection was given as they were wrapped in polythene wrapper. Score of 4* based upon previous and subsequent experience in that they appear to work. Subsequent double package - one was complete but other still suffered some damage although 4 were still complete so the dust was suited as a dose to my 2,000gal pond.

Seemed to do the job
Bought this as my pond was murky and need some help to clear the water. It was very simple to use, threw in 2 of them for the first treatment as recommended on the instructions, after a week the the water started to look clearer, put another one in two weeks later and helped massively. I will continue to use these every few weeks to keep the pond healthy.

Clear pond, great value product.
Did what was expected, took a few days and a few treatments. But very good value compared to other products on the market. Make sure you clean filter boxex regularly after treatment, and for a while after. Check that before thinking you need more treatment eg pond looking a bit murky again as I found it was that which was ca using it.

Works eventually
At first no improvement, but then added a second dose and two days later like magic the water is clear. I’ve actually got more fish than I remember now I can see them!!
