envii Sludge Klear Pond Sludge Remover, Natural Bacteria Sludge Buster Digests & Controls Organic Waste, Safe for All Fish & Wildlife, 6 Tablets treats 30,000 litres

Went from Murky to clear in 1 week. Cleaned filter daily and Water clarity is perfect now.

Quick delivery of the product.Having done a major clear and tidy of our pond early this summer we disturbed a lot of sludge and algae and our normally clear water became very murky.Using this with pond klear and it's slowly working. I can see where sludge is clearing off the stones on the bottom and our water is getting clearer.You must clean the filters and pump every few days. I have been mesmerised by how much sludge they're getting.

Works really well, brings sludge up through filter box.

Using a pond net to scoop most of the sludge out was the best option to be honest. Use a filter with UV light to kill the pond algae and clear the water over time. Sludge Klear was average.

Great item for clearing up the sludge, and although a little dear it works and so is value, give real water clarity ansd lasts just over four weeks when it needs tobe repeated

It works well

Don't bother, it doesn't work. Used tablets in watering can, as per instructions. Still cloudy diety pond water. So disappointed.

Excellent 5-star service from this supplier. The goods arrived at the allotted time and were well packaged. The goods were exactly as described by the seller. I have no complaints or problems with the overall standard of services as supplied by this seller or with the product.
