Low Alkalinity High PH Problem

(1/5) > >>

DJJ:
I just changed my water and am in the process of balancing things. I am having a hard time getting my PH and Alkalinity in the proper range. Every time I try to raise my Alkalinity, my PH goes up as well. If I try to lower my PH, my Alkalinity drops as well. I presently have a PH of 8.0 (high) and Alkalinity of 36(low). Can somebody please HELP! This is driving me batty. Any ideas would be greatly appreciated!

Prioritize the alkalinity and the PH will follow.

Add PH Up into your tub...They pull on each other so if you keep raising the PH, it will force the alkalinity up, while eventually pulling PH down.  It's a fine balancing act.

So I have 2 conflicting ideas. Raise the Alkalinity and the PH will follow. Raise the PH and the Alkalinity will follow. Hmmmm.

I'm having the same problem. My alkalinity starts out low, 25ppm, with a pH in the high 6's. Once I get alk to 80+ppm the pH shoots to 8.6 - 8.8 and stays there. Powder pH down doesn't bring it down. I'm on well water which could have something to do with it from what I read. Also, when adding bromine, I get green scum at the water line which I also read indicates the bromine is reacting with metals in the water. I also know I have hard water b/c the builder had to install a water softener based on the well report. Outside hose bibs do not get softened water fed to them.

I just drained the tub today and started over, refilling using a 1 micron hose attachment filter. I've read of other having success with this method. Did a quick alkalinity test of the filtered water, and it read ~25ppm so no difference starting out, but hopefully the filter nabbed whatever was spiking the pH when the alk increaser hits.

For reference, I'm using Spa Guard chemicals b/c thats what the shop near me sells.
