    Pool manufacturer calls for high TA

    San Juan Pools (fiberglass) says to keep TA between 125 and 150. Is that true for all fiberglass pools? Why that high?
    12,500 Gallon fiberglass, chlorine,1 skimmer, 2 returns adjustable eyes, sand filter, automatic chlorinator (don't use except for vacation or if CYA gets low), 1-1/2 hp EcoTech motor on Pentaire Supeflo pump some trees.

    Viking also states the same range in their manual. But much like many of their level recommendations, they are outdated and/or do not reflect the latest in industry testing or lessons learned. We know that TA serves as a buffer to work in conjunction with pH. It also plays a part in a pool's calcium saturation index level as it relates to healthy plaster. But we also know that a high TA, much like those recommended in the general pool industry, tend to increase pH which in reality is the most dangerous effect. By maintaining the TA at the TFP recommended levels, TFP has learned in some 10 years of analysis that a pool's pH will be more stable, thereby reducing the amount of adjusting required.

    As you look further, you'll see the same issue with their recommended FC and CYA levels. Again, antiquated guidance that has yet to catch-up with today's standards.

    You should maintain your Ta level where it makes your PH the most stable.
