Envii Sludge and Pond Klear Xtra - Pond Treatment Pack - targets unwanted organics during winter.

Great stuff ! Start using early in the season to ensure a lovely clear pond . We have a wildlife pond and this stuff is brilliant and no taxis chemicals too . Would definately recommend you look no further than this British product !

I really love Envii products. They're safe for my nature ponds and do the job of "ten" pumps and filters ;) . I bought this as a two needs in one purchase and as I'm a regular user of Xtra Clear, I thought I'd give sludge clear a try. Absolutely pleased. My only real complaint, if you can call it that, is that the Xtra Clear is quite expensive for the amount you use and if I can say, it's tricky to get the product out once you've reached a half empty bottle.I've tried "cheaper" brands and they just didn't do the job that Envii does so I'll stick with it but given I have four nature ponds we we are literally surrounded by trees, one of the ponds is absolutely chock full of tadpoles year round, so we have a need to keep the water at a livable quality for plant and animal life either amphibian or the local wildlife that drinks from the ponds so I will keep buying your product despite a slightly painful price. I wish you sold it in much larger bottles so I didn't find myself spending nearly £100 just on ONE product to treat all four of my ponds, and while my ponds are not huge, they are large enough that I need three bottles of Xtra Clear to do one treatment, or a second as in spring when they've been sitting frozen for a few months and this doesn't take into account other products required. Again, the products are very good I won't be buying another brand any time in the near future. :)

The water in our small pond (approx 600 gal) had been gradually getting worse over the past 12 months and we'd tried various other treatments without success. As a last resort, I bought both the Envii Sludge and Pond Klear Xtra in May and followed the instructions to the letter. Cannot tell you how delighted we are with the result!! The water has been crystal clear for the past few weeks and we can once again watch the fish swimming happily way down to the bottom of the pond. I would not hesitate to recommend these products. Must stress however how important it is to clean out the filters and have patience!

This works but is a bit expensive.

My pond was very dirty, I could not even see the fish . After about 2 weeks the water is definitely clearer and I can now see my fish again. The fish are also a lot more active than before.

It did a really good job - needed a few treatments but made such a difference. Plants, frogs and fish look happy, too.

We had to use this product twice and wait a couple of weeks for the full effect but if you are patient you’ll get great results

Our pond had sludge which was sitting quite deep on the bottom of the pond which consequently made the whole of the surface a green colour. After using Envii for approx 3-4 weeks the pond cleared and we can see right down to the bottom of the pond. Great product. Would recommend.
