Thanks, Brett for getting back.
The concern I have is keeping my tanks spotless. I do try to empty them only when they are full and I flush with clean water for at least 5 minutes. I have recently noticed an odor from the gray tank through the bathroom sink. I had been keeping the gray valve open due to the fact that we use a washing machine and dishwasher.
Would leaving the gray water valve open cause this odor? I had heard that this rid-x was a good product, but I questioned it when I found out it was for septics. I am currently using tst in black tank only. Should one use it in gray as well? thanks much.
