court, read the "lowering alk" sticky over and over. It does indeed work just like it's typed.

One thing I would highly recommend based on my experience is to not use the fountain to aerate UNTIL you get the ph down to where you want it. Monitor the PH and when it rises to the point you need to knock it back down again (assuming you still need to lower your alk some more) turn off the fountain and again lower your PH, then begin aeration.

Good luck
