Hello All,
I bought a new home last summer with a salt water pool and I've really dived into the pool maintenance thing since. I bought a K-2006 Salt test kit and with the help of this forum and the calculator, keeping my levels have been relatively pain free with the exception of my Alkalinity levels which have been plaguing me since day one. Since I bought the house late in the pool season I just put off dealing with it until this spring because at the start of this pool season I was going to try introducing borates into my system and figured at that point I could utilize the Borax to achieve what I needed. When I reopened the pool I found some of my levels were off so I have some other things to take care of as well but I wanted to tackle one thing at a time. Specifically my CYA has dropped to 50 from last seasons 80. I assumed this would only affect my chlorine levels so I haven't gotten around to bringing that back up yet but if that could be affecting it please let me know. Back to my efforts...
Starting:
PH: 7.4
TA: 140
My understanding from doing research is that Borax will raise PH without raising Alkalinity so the idea is to bring the PH and Alkalinity levels down and then just raise the PH back up with Borax, rinse and repeat so PH doesn't get dangerously low. I went ahead and bought a few jugs of Muriatic Acid as I had just run out and several boxes of Borax to start. I wanted to do a test run of this before I cleaned out the store of Borax, especially because it would be harder to lower my PH after the borate levels were up. I added enough Muriatic Acid to bring down the PH to below 7 on the test kit (added enough to sit around 6.8) which also brought down my Alkalinity levels down to ~125.
After Muriatic Acid:
PH: 6.8
TA: 125
I then went ahead and added a couple boxes of Borax and waited a day to test again. I just tested the water now and that's what triggered this thread. The levels for both are right back to where I started.
After Borax:
PH: 7.4
TA: 140
I feel like I'm back to square one. I know I haven't provided all of the figures for my pool here but I thought these were the relevant ones for this particular discussion.
Thanks for any advice you may have. My understanding is that aerating the pool is another option for raising PH without raising Alkalinity but I wanted to introduce borates into my pool anyway so I thought the Borax route was my best bet.
