Good Day,
A friend of mine just replaced his Vinyl liner, and we filled it with water. It holds a mere 7,000 gallons.
Right now the pH is at 6.8, Chlorine 1, Combined Chlorine 0, Alkalinity 50, CYA 0, and Calcium 110.
Being this is basically a plastic pool, the calcium does not matter right?
Everything is sparkling clear. Without doubt, the PH needs to be raised to around 7.4, which should also bump the Alkalinity a bit. Hence, it is my supposition the first thing to do is to raise the pH with some Soda Ash... and the Pool Calculator says to add 19oz (with TA of 50)... After doing this the pH should be reasonably well balanced around 7.4 AND the TA should increase to around 70.
After this, it stands to reason that we will need to add about 32oz of Baking Soda to then raise the TA another 20 points bringing it to 90 stabilizing the pH.
Now, it also makes sense we NEED to raise the CYA (AND the Free Chlorine), but we do NOT have any stabilizer. Why not just use Dichlor shock? I bought about 12 packets of it before I knew how much it messed with the CYA of my plaster pool. It seems now it would be ideal because it A) Dissolves very fast and B) Is almost a 1:1 in that if we raise the pool's chlorine to 20 ppm with it, the CYA should head to around 18... Let the chlorine fall to about 5 ppm then raise it to about 15 ppm.
What do you think? Reasonable?
