## Questions & Answers

**Q: Will this work on collected washing up water? We are saving the pors water and it starts to smell in the butt very quickly.**
A: Try butt cleaner it worked o mind but no soap in mine

**Q: Will this work in a 1000ltr bulk container the rainwater is brown & smelly**
A: I have a 30 gallon water butt and use the recommended amount of tablets and it certainly worked for me.  My rainwater was brown and smelly and now it is reasonably clear so should imagine it would work for you, it might just take a lot of tablets!

**Q: Will this work on collected washing up water? We are saving the pots water and it starts to smell in the butt very quickly.**
A: I don’t honestly know but it might work. My water butt wasn’t brilliant, moss and mosquitoes. I used 2 tablets and 2days later it was clear and fresher, even the mosquitoes have disappeared. I use a tablet every other week. Very good. Recommend.

**Q: Will this help clean the water for my lucky bamboo in a vase without having to change the water?**
A: In theory yes, however we wouldn't recommend it as a vase is a much smaller volume of water than this product is designed for and it would be exposed to more direct sunlight and UV which will make it harder for the product to work efficiently. It's not the intended use.
I hope this helps with your query.
Thanks,
