Different recommendations for quantity to add

[EndlessSummerAZ]

Looking for some help here. All values and chemical selections remain the same in the pool math app. I’m getting different suggestions on quantities to add.

If I go into Ph initially the 14.5% acid is defaulted (which is what I’m using). I get one suggestion of amount to add at 66oz. If I click on the “lower with” box and select 14.5% then the app changes the value of what I need to add at only 27oz. Quite a large difference. Any insight?

Any insight?

The value for pool volume may have changed.

The value for pool volume may have changed.

I would have to go in and manually change that in another field which I haven’t done.

I plugged in your numbers into my PoolMath and it suggests 66 oz.

@Leebo It looks like there's a bug. When you select a different chemical to lower pH, sometimes it keeps calculation from the previous chemical but displays the new chemical.
