sorry, meant to say I'm running the res @ 6.1 PH ... the tap water is mid 7's. The runoff is also steady at 6.1

I rinsed/soaked (a lot) w/ non-ph'ed water but then flushed w/ PH ... so most likely the flush didn't really affect the higher PH'ed rinse.

I think you're 100% correct. I've added PH down to 5.9 ... i'll check the res later tonight and add more PH down accordingly. I've learned my lesson w/ pre-soaking hydroton!

And thanks again Stinky
