do I need to address low pH right now?

I just started a SLAM tonight. I got in a hurry and checked pH before dumping chlorine in and it was high - 8.2 so I just eyeballed some acid (oops) then went to do the rest of a full test while that mixed. It read as low as the scale could read 6.8 maybe a little lower???

should I add anything? I have borax, washing soda, and baking soda all - so if I need to fix immediately which is best?

FC - was 0, now should be 16 after adding a gallon of 12.5
TA - 60
calc - 150
CYA - 40 (water cold and getting dark so may need to recheck)
salt - 2600
borates - 30

temp 55 F

Yeah you may want to deal with it soon. Low pH is harsh on fittings, equipment, and in your case if left longterm, you vinyl liner might get brittle and dry.

Have you discovered PoolMath yet? Either the app or the older version at the bottom of this page??

What do you have at the house now? Borax or Soda Ash. I'd use whichever you can get your hands on easiest.

I too find the old web version fastest to use much of the time, especially when I'm answering others questions.

In that case, my own personal preference is for Borax. Use the PoolMath page to hook you up with 7.2 being your goal. You might have taken your pH lower than 6.8 so it may take a couple of steps.

May the Force be with you!

and remember..... don't add any more chlorine until this is settled- a FC > 10 skews the pH reading. It usually makes it appear higher than it is.
oh yeah. well as green as it was getting, I bet it will drop quite a bit by morning. I will go put 1/2 the amount of borax and see
what things look like in the morning. thanks!
