algae and high ph

[aylad]

When should I add Muratic acid to bring PH down? After algae is gone or do it now?

Your chlorine is going to be more effective at the lower pH ranges, so bringing it down now would be fine...as long as you know your levels are accurate. High chlorine (I'd say above 10) will skew your pH test results upward, so just be careful not to drop it below 7.0. I'd shoot for 7.4 while your chlorine is high just to give you a little wiggle room.
