9 was the number of drops of R-0006 I need to add to get to the 7.4 maybe I quoted it wrong in my post? I had to add 9 drops and then crossed reference the chart in the book.
Ah thank you for explaining!Use PoolMath. Put in the pH value you tested and your goal pH.
It is safe to add acid to the pool water.
Sodium bisulfate (dry acid) leaves sulfates in your water. Sulfates build up in the water and they corrode metals. The rare earth minerals on your SWCG plates are eroded and your SWCG will no longer work.
Ok, so don’t mess with ph at all until slam is finished? I feel like I am SO CLOSE, but still experiencing fc loss overnightDon’t worry about testing pH right now. Whenever your FC level is above 10 your pH test is not accurate.
That is why we always get our pH to 7.2 before starting a slam.
