g'day, I have a couple of x24 pot RDWC systems,
and have noticed a build up of slime. even with running maximum UC roots solution
at the end of every run I do a 2 day flush using 4L of hydrogen peroxide and 4L of strong bleach, and obviously 2-3 water flushes after that.
regardless there is still a scum build up in the pipes afterward.
I'm wondering if I could run a strong chlorine solution , or similar ?
any advice would be greatly appreciated .
