MDVPC!!! your PPM from the tap is at 450? That is wild. Where I live its one of the few places that they greenlit recycled water
and last few times I tested when i was growing hydroponics was around 150ppm. could you link me to the RO system you purchased. I dont believe the RO will remove the chloromine correct?
Although from what raybo posted it doensnt seem to be an issue.
I've been leaving my water out in the sun for a in of 24 hrs to let it evaporate some of the crap. Is it worth it?
On my seedlings I use nothing but distilled water.
