    What naturally (not which chemicals) lowers pH???

    So, I am new to the TFP method, and loving it. Before finding this site, I was using only DiChlor in my pool. That took my CYA out of control (which is what brought me here), but also always kept my pH low. I was always buying tons of pH up, and always seemed to have a low pH, no matter what I did. So, I know that will end this year. Now, using the TPF method, I will be adding bleach, and not lowering pH with my DiChlor. So, on to my question.

    I know that aeriation (splashing, return jets rippling water, etc) will increase my pH. I also know that acid will bring my pH down, as well as rain water, since rain is acidic. But, will any other NATURAL occurrence lower my pH?? From what I see, it looks like I will never need to add something to bring my pH up again, and should be keeping plenty of acid on hand going forward with the TFP method.

    Am I missing something here? It would seem after opening, and once I achieve proper balance, I will only be lowering pH, unless we get tons of rain dumped in the pool.

    Re: What naturally (not which chemicals) lowers pH???

    If you're worried about toxicology, Muriatic Acid (AKA Hydrochloric Acid) is about as simple a chemical as you can get. One hydrogen atom, one chlorine atom. Both of those atoms are in your pool anyway...

    Spa: 525 Gallons, Coast fiberglass spa of unknown vintage and suspect previous care with a 2-speed main pump and a blower motor, both 4HP. 3-step bromine sanitized.

    Re: What naturally (not which chemicals) lowers pH???

    I'm not worried about adding Muriatic acid. I'm just curious if I am done with pH up (or Borax now that I am on the TFP method).

    For 8 years I have never needed to lower pH, because the junk I've been dumping into my pool has always been lowering it. Now that I will only be using bleach, which is pH neutral, I'm just curious if I am done every needing to raise pH (other than at a opening, or after a major storm). From what I am reading, it seems like my pH will always be rising, unless there is something else in nature that drops it. So, I thought I would ask what naturally lowers it.......

    It is very likely that you will not need to raise your pH anymore. I am not aware of anything that naturally lowers the pH besides what you've mentioned already.

    Ditto what FPM said. I also haven't used but a few cups of acid in the last 8 or 9 years. My pH sits dead on 7.5. I said that to say, don't imagine problems that may not exist. You may find that your pH is very stable.

    ya once you figure out what your pool prefers for TA level, you can get it to stabilize ph levels.

    both my first plaster pool and current vinyl in ground have ph at 7.5 all the time with no swings.

    She's going to be getter the most beautiful pool water she has had in 8 years. What more could she want???

    I just used the first months savings to order a pump for liquid chlorine. Once I get that hooked up to my watermatic, I change my signature from "uses DiChlor"
