First numbers from the new refill....

DLO · May 20, 2009

Temp 68F, FC-5.5, CC-0.5, pH-7.3,T/A-300,CH-330,CYA-<20 (added enough to get 50 once dissolved)

metal sequestrant used to treat 40k as i was filling. Been backwashing the filter as needed. Pump running 24/7

The water has a blue/green tint with a slight haze.

Since fill was complete (yesterday) the autocover has been left on.

Suggestions?

Your TA level is very high. Until you can get it down you want to make sure that the PH never goes over 7.5. You can read about lowering TA at Pool School.

I built aerators for both returns last year. I planned on lowering the pH and aerating. With the TA so high, how much should i overshoot the recommended acid addition, since the pH will be hard to lower? I remember last year, I added almost 4 times the recommended (Via bleach calc) acid and barely got the pH to react.

What would you suggest for the water color/haze.....and should i wait to fix that until after i get my TA in line?

You want to get the TA down a bit before you shock (if you shock).

The haze will probably clear up from normal chlorine levels and a little filtering. If it doesn't, you will have to shock later when the TA is a bit lower.
