Soda Ash vs Running jets to raise pH
What you guys think

Intial pH 7-7.2

Most hot tubs have no problems with raising the pH due to all the jets running. Just run them generously and make sure they break the surface.

If you need to raise pH, always do aeration first. Usually hot tubs have an issue with too high of a pH, not too low of one due to lots of aeration. Turn on both your pumps and open all the air valves. Check pH every 15 minutes. If it doesn't budge after 15 minutes of this, you'll likely need more TA. At this point you can add washing soda to raise pH and TA, or at baking soda to raise TA and then run jets with all air valves open again.

What is your TA? This determines how fast the pH will rise with aeration.

My fresh fill TA is around 80 is that high enough ?

 

[jseyfert3]

You should see pH rise with that TA still.

Crazy enough... My tap water tested 7.4 - 7.5
I filled tub.... Primed system run jets for 5 minutes and Im 7.88... Uhhh

And now you know what I mean.
