## Features

- Clears Sludge & Treats Green Water – Envii Winter Pond Treatment provides billions of beneficial bacteria & enzymes to your pond to help clear & reduce sludge whilst helping clear green water in garden ponds.

- Works in All Ponds – Winter Pond Treatment can be used in ponds with or without a filtration system. Due to our unique formula, filters are not required to succeed. Alternatively, you can also apply this to your filters should you keep them running all year round.
- Safe for All Fish, Wildlife & Plants – Containing only natural ingredients, Winter Pond Treatment is completely safe for all fish including sturgeon & koi, all wildlife and plants.
- Large Treatments – One packet will treat up to 60,000 litres, containing 12 tablets. Each tablet treats 5,000 litres and is completely natural, meaning you can’t use to much per treatment.

## Questions & Answers

**Q: Hello Instructions mention turning off uv lights how long should I leave them off after treatment?**
A: We advise to leave these off for around 2-3 days.

**Q: Does it clear brown, murky water? Cleaned the filter and ph- level is ok.**
A: Hi this product is an extremely concentrated tablet form of friendly bacteria which ultimately will help control nitrate levels and help to break down the decaying organic matter already present in the pond. Over time with correct use this product would certainly help towards the water quality of your pond but I feel if you are wanting to clear dirty water a lot faster I’d maybe suggest a product clears cloudy/dirty water by clumping the particles and sinking them to the bottom of the pond. The envii product in question would then certainly help in breaking down this clumped/sunken debris on the pond floor and with continued use and regular maintenance of the filter your pond water should clear up and remain clear. Hope this helps.

**Q: Hello,I have a lake of 3/4 of a acre,do you sell anything suitable for that? Or just buy multiple packs of this? Thanks**
A: No you need our Lake Klear Klear product,  Winter pond treatment is not suitable

**Q: Can I use this now I have frog spawn in pond**
A: Yes, no problem or conflict with frog spawn
