sorry this is not an answer.

I have been using it for a while now. I have no idea if it does anything. I am actually wanting to know the answer to this question too. I know it is meant to be used with a drip system. Yet it also says on the bottle it helps with salt build up and helps the nutrients not (do not know the word) turn to other chemicals...
whats that word?
anyway I am wondering if I should stop using it. I am running the entire house and garden line with amazing results. (for one of my grows) yet I would really like to know the science behind drip clean. I wonder if I even need it for ebb and flow style.
What is in it?
Is it worth it?
I know it has quite a bit of K
Do I really need it for ebb and flow?
I know with using it I still get salt build up in the medium. I still flush the medium every couple weeks. I know it does not prevent salt build up. It may help it?
