Excellent product used before cleared the pond of brown water to crystal clear.

good product

Works

Bought this to try and clear our pond. I cannot say that we saw any improvement at all.

I’ve used this before and helps breakdown the sludge I only have a 400 litre pond but with new pondtec 10000 filter system and this the pond is now crystal clear in two days ! It won’t get rid of algae, I use a different product for that and a UVc clarifier !

The media could not be loaded. Our pond was very green soupy and sludgy I purchased sludge bomb, a pond clear bomb and also changed my UV bulb, days later pond is getting much clearer and we can now see happy fish . I have attached a video , would highly recommend.

Easy to use but am waiting for results, which is ok because nothing works instantly.
