## Questions & Answers

**Q: Can you tell me how much of this product I should use in an 140Ltr wild life pond please?**
A: 1/4 of a tablet is about the smallest you can break them into. That will be fine. Treat every 14 days as will be a heavy dose and any more frequent will overwhelm pond and bacteria will fight each oth

**Q: When you use this does it affect the oxygen levels in a koi pond and is it suitable with a bubble bead filter**
A: Susan, when any bacterial treatment works it uses oxygen but as the bacteria are microscopic the amounts used are small and if you have air being introduced via a pump this will be plenty.  One key thing to remeber is to wash up your filters regularly as it will break up a lot of sludge which will get caught by your filter and we suggest every 2 days.

**Q: Would this help in a pond with no filter? We have a 'wildlife' pond so don't have any filters or anything like that. No aerator either.**
A: It will help out for sure.  The only thing to bear in mind is that it can take a week or so for the effects of the bacteria to show.  You will also find it will reduce the levels of algae/blanket weed in the pond too.  I hope this helps.

**Q: Does one have to use this dose every 5-7 days all year round. My pond is 13,500 lites so I’d be spending almost £30 a month?**
A: good morning..   I only used it once.. our pond is approximately 4000 gallons and I hovered the sludge out twice back in the summer.. so I suggest you don't use it all year round as the instructions say don't use under a certain temp.. maybe you have too many fish or your filter system is not big enough.. you do need to clean the bottom of the pond every so often.. this is how I look after my pond and all is ok
