Product Description

All products are designed and manufactured by a leading UK water garden brand; Blagdon – The Pond Masters. With over fifty years experience in fish keeping and water gardening, you can be sure that all products manufactured by Blagdon will not only be beautiful, but designed specifically for successful fish keeping and water gardening.

We know that throughout the year ponds accumulate debris, dead plant matter, uneaten food and fish waste. If this is left untouched, it forms an unsightly, unhealthy layer of sludge at the bottom of the pond. The Bio-Active Sludge Buster's unique blend of bacteria and enzymes break down this sludge leaving your pond with a clean bottom.

The bacteria are species that use oxygen locked up in the sludge for their respiration, preventing a lack of oxygen in the water for the pond fish and other water borne wildlife. You can also add Sludge Control to your filters to reduce maintainence.

There is also a sachet alternative to this product, which can also be found on Amazon, just search for Blagdon Sludge Buster.

All in all, why look any further for the perfect product for your pond, when you could go with Blagdon: The Pond Masters?

Have been using this product in my pond all summer in conjunction with an anti algae product and am delighted that it actually does what it says on the label and the water stays very clear.

Good price. Sent quickly. No Hassle.
Have only used it once so far and it certainly helped clear the sludge in my small 200gal pond.

I have tried a few products on our pond but this is the one that really works. Repeat order so that should say it all. I will be ordering again next year I suspect when the weather warms up again. It does exactly what is advertised.

My small garden patio pond (250 liters) turned from algae green to brown in a matter of days and I had nothing to help on removing the nutrients.
All my pond consisted of is a solar powered air stone making oxygen for the pond and a few floating plants.

I slightly overdosed on the recommendations but had no major problems as following day, bubbles appeared on top of the water film. Hoping I hadn't lost any fish as water too dark to see anything but after standing still for a few minutes and placing some food in, could see one of the three fish pop up to nab the pellets.

Slowly each day I could see the water clearing up but I decided to also go for a UV pump as this would be additional help also with removing some of the organics. I decided to dose Bio-active and leave pump off for 5 days. Started the pump and in couple of days, it required a good clean and I'm happy to say I have a cleaner pond and I can for one, see the white label on the pond pump from the bottom.

This product does really help clear up the pond but I think if like me, you have no mechanical biofilter, this help but you do need something to go a bit further with clearing the water.

Easy product and no plant/fish casualties.

Un glamorous and utilitarian is this product but it's not trying to win a beauty contest . It does what it says on the tin - clears sludge from my two ponds . It is simplicity itself to use, the instructions could not be clearer and best of all - it works. I only need to use the treatment twice a season and it maintains crystal clear water . Best buy of this type I have used.
