how many gallons does this treat

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!

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?

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.

I have a 600g pond. I dosed it last night. Water is still black. How long does this take to clear water?

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!
