I'm having a bad pH morning

I have a chiller Problem is that I run a *lot* of lights. More specifically - 7x 250HQIs + 3 x 150HQIs.

The photoperiod is 1pm-8pm

The heck with the chiller, I think it's time for a walk in freezer!
Are you on Boston Edison Christmas card list?

Are all 10 MH lights on the same tank?
