One source says one thing and another source says something totally different.
A local pool store stuck one of their dealer Pool Care guides in the bag with my new skimmer net. It's produced by Sun Pool & Spa Products. I was perusing through it while relaxing by the pool this evening.
I found this info odd, considering everything I've read in other pubs, forums and products. According to Sun:
TA should be maintained between 120 - 150 ppm. "To prevent pH from drifting or bouncing, the proper amount of acid buffers - or total alkalinity (TA) - must be maintained in the pool. Test weekly to maintain TA of 120-150 ppm. Low TA can result in pH bounce and fluctuations, as well as corrosiveness and staining. High TA can also cause pH to bounce and the possibility of coud water and scaling."
Most every other source I have on hand says TA should be maintained between 80 - 120.
Calcium Hardness is recommended by Sun to be:
200 - 250 for concrete pools
175 - 225 for vinyl pools
I'm doomed before I start with CH as Phoenix water is very hard and has a lot of CH. Other sources say CH is good between 200 - 500, yet others say 200 - 400.
The booklet says the pretty typical pH 7.2 - 7.6 and Free Chlorine 1 - 3 ppm. Nothing at all in the booklet about stabilizer/CYA.
Sooooo, what do you experts say about it. Are they right or wrong?
