How To Lower TA In Pool/Hot Tub/SPA with/without MA & in WINE

A stable PH level doesn’t need lowering TA for, at least not for many reasons. If your chlorine is low and you are beginning to experience cloudy water, then that might be algae growth starting and you can shock the pool. However, if your TA, PH and CH are high at the moment, then that could cause water cloudiness but I suspect the growth of alae if your FC level is too low. The appropriate FC is based on your CYA level.

How To Lower Ta In Pool/Hot Tub

So, make sure you actually have one of the above issues before lowering your TA.

The acid/aeration process to lower TA:

  • Add acid to lower your PH to between 7.0 and 7.2 (this also lowers TA)
  • Aerate until PH rises to around 7.6 (the only way to raise PH without also raising TA)
  • Repeat steps 1 and 2 until you reach the desired TA.

Using Dry Acid/PH Reducer or Muriatic Acid, your PH level can be reduced. Check your test kit and see if it comes with an acid demand test. If it does, you can use that to precisely calculate the amount of acid needed more precisely. Now, wait at least 30 minutes after adding acid, with the pump running, before you test the PH again.

As for aeration, you can use waterfall (BUY ON AMAZON), spa jets (BUY ON AMAZON), SWG (BUY ON AMAZON), fountain (BUY ON AMAZON), return pointed up so it breaks the kid splashing, air compressor (BUY ON AMAZON), rain, surface etc.

The process of TA lowering can take some hours, days or even weeks, depending on the level of aeration you’re doing and how far you needed to lower your TA. A lot of smaller bubbles are more effective than few large bubbles. Lowering the PH back to 7.0-7.2 more frequently will also speed up the process, though that can get tedious.

It is basically the acid which lowers TA. Adding acid lowers both the TA and the PH. Then aeration raises the PH without changing TA. NEVER use chemicals to raise your PH during this procedure (unless your PH accidentally goes way too low); that will just raise your TA back up, which is exactly what you are trying to avoid.

There are lots of common myth that you can lower TA by adding “slugs” of acid to the pool. While any addition of acid, slugs or otherwise, will lower the TA, adding slugs of acid can damage the pool surface and may lower the PH far enough to cause other problems.

How To Lower Ta with Muriatic Acid

Muriatic acid added to the pool can lower the TA down between 100 – 125 ppm, then add 20 Mule Team Borax to raise the PH to the recommended levels between 7.2 and 7.8 since MA reduces PH levels too.

How To Lower Ta Without Lowering Ph

This is not possible. There is no method of lowering TA without affecting the PH. But, you will need to raise the PH to around 7.8 first using 20 Mule Team Borax, which doesn’t affect your TA, then add MA slowly to lower both PH and TA.

How to Lower Ta In Wine?

You can use potassium bicarbonate or potassium carbonate (KHCO3 or K2CO3) to lower TA by only 2-3 g/L. If you need to take away acids, then it is better to use the double-salt deacidification with calcium carbonate.

How To Lower Ph But Not TA

The only means of lowering PH without lowering the TA is to inject carbon dioxide in the water. So, if you need regular acid, this reduced both the TA and the PH. But as I earlier stated, you can have a lower TA if your pH isn’t dropping over time. So add acid first to lower the pH closer to 7.5.
