## Questions & Answers

**Q: how many gallons does this treat**
A: The container comes with a soup about  tablespoon sized and there is messing table on the container of how many scoops per 100 gallons. I have been using it once a week with 2 scoops and there's about 6 months worth in the container, by my guess. I hope this helps!

**Q: What are the ingredients? Does this contain peroxide?**
A: No peroxide

**Q: Hi my water is clear.  But will this work for cleaning up a sludge spot in my pond that is about 4X4? Or should I go with a pellet sludge remover?**
A: This product is excellent  I use it with either API pond flush or Microbelift PL. A super self discovered secret is mix 2 parts liquid bacteria above with one part pond zyme to make a cookie dough consistency. Roll it into a ball and drop or toss into pond directly into dirtiest sludge spots in the bottom of your pond. We use this technique in show ponds at a pond outfitter. Tried and true for over the last year. Unplug this UV’s for at least a day. You can substitute half barley extract if you’re having an issue with string algae.
I then supplement with whatever remaining liquid you need to add for the size of your pond.

**Q: I have a 600g pond. I dosed it last night. Water is still black. How long does this take to clear water?**
A: I was not a fan of this products performance. I've not had Black problems before, but lots of Green especially in Spring.  I think water changes and UV Sterilization unit was my clear water help!
