Review: 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. Review: 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. ## Features - Predosed ready-to-use snuggets that can be put straight into your filter - 1 pack contains 6 doses, each treating 4546l (1000G) - Economic two pack which should be dosed every 1 - 2 weeks - Packed with beneficial bacteria that breaks down organic mater to reduce sludge - Safe for Koi, community and wildlife ponds, and can be used year-round ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07C2TMN69 | | Allergen Information | Allergen-Free | | Best Sellers Rank | 11,049 in Garden ( See Top 100 in Garden ) 80 in Water Garden & Pond Treatment | | Brand | Swell UK | | Brand Name | Swell UK | | Country Of Origin | United Kingdom | | Customer Reviews | 4.0 out of 5 stars 502 Reviews | | Item Form | Tablets | | Item Type Name | Water treatment | | Item Weight | 0.37 Kilograms | | Item form | Tablets | | Item weight | 0.37 Kilograms | | Liquid Volume | 12000 Gallons | | Liquid volume | 12000 Gallons | | Manufacturer | Swell UK | | Manufacturer Part Number | SWLATREAT-Parent | | Model Number | SWLATREAT-Parent | | Target Species | Fish | | Unit Count | 2.00 count | | Unit count | 2.00 count | ## Product Details - **Brand:** Swell UK - **Item form:** Tablets - **Liquid volume:** 12000 Gallons - **Manufacturer:** Swell UK - **Unit count:** 2.00 count ## Images ![Swell Control Green Sludge 2 Pack.

It didn't do much to the blanket weed but it certainly cleared the water and I can see the bottom of the pond which is about 3'6" deep. Since then I have dropped in 4 sachets now and then but I am using Green Go for the blanket weed. All is working well so I suggest you just follow the instructions. **Q: do you have to turn off the uv light when using this or leave it on** A: The uv light was on all the time **Q: Is the pond life save when using this** A: Yes all pond life, fish, plants,frogs,dragonfly s etc are very safe **Q: My pond only holds 25 gallons so how much should I use** A: Not a lot. A calculation would give about 1/40 of a sachetbut if it were me I'd probably drop in 1/2 of a sachet. That should work well without harming anything as it's a natural product. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product. *by M***D on 29 July 2021* 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.
