Hey everyone. I put some "stuff" from camping world into my gray tank that was supposed to "eat" all of the bad stuff. I went from 32 gallons of water to 42 gallons. We are headed in the right direction. I put some more in the tank and I am letting it sit for a week. Hopefully this time I can get the full 50 gallons in. Thanks for everyone help in this matter. I am out on the road at work, or I would list what the product is. I will let everyone know when I get home.
