The lower TA will definitely help your battle of rising pH and you should be able to keep your pH around 7.5 without too much difficulty. Your CH is already elevated at 350 and helps compensate for the lower TA that I am proposing so your water will be in near perfect balance at the lower TA levels (currently, your water is over-saturated with calcium carbonate, but not so much as to cause cloudiness or scaling).

Thanks Richard,

I had read in another post where someone even lowered there TA to 50 to really fight the rising PH. Next summer, if I see that TA of 70 still doesn't do the trick, can I try lower or should I avoid the risk?

Promise this is the last question.

Thanks again
