Ta help

[Meaty]

My TA drifts down to 30ish as i add acid over time. At those lower levels I don’t have to add acid as often. Why not keep it at 30? What’s the advantage to keeping it higher?

Thanks

TA is what buffers your pH. TA too low can let your pH crash down and your pool can suddenly become dangerously acidic. At 30 you are skirting along the edge of a cliff that your pH can fall over.

I would be very careful with small acid adjustments as any acid can push your pH over the cliff.

Once your TA hits 50, the pH should not rise above 8. You likely are adding too much acid. Do you have Poolmath logs you can share?

What model test kit are you using?

I have the TFT test kit. When i get 8 ph I add the amount of acid the pool calc tells me - typically 15 ounces every 3-4 days.

Leave the pH at 8. See if it stabilizes.

Confirm you're using a 25 ml water sample.

For the TA test, are you adding drops until there is no further color change?

PoolMath is just a calculator. It's important to not blindly follow it. You're adding too much MA (stop adding acid). See where your pH stabilizes.

Its stayed at about 8 PH, 60 TA for the last week. Will i get calcium scale if i leave it at these levels? Thanks

Use PoolMath to determine your CSI.

Its at 750. Pool math says to replace 28% of my water - that seems extreme. How do i manage the calcium levels more proactively in the future? Is 750 a level that will cause scaling? Thanks

Enter your test results into PoolMath and let us know what the CSI is.

.76. Seems like scale will form. If i lower the ph to 7.2 then its -.04

With an elevated CH, you need to keep the TA and pH more controlled. You get rain. Use it to replace pool water when you can.
