We had our pool installed last year in June. My first season with the pool, I went through 3 gallons of MA. I opened my pool on April 18 and I am now (already) on my fourth gallon of MA. My return does not break the surface. The main way my water is getting aerated is by the wind. Right now, it's relatively calm at 11 mph, but we've had quite a few gusty days...sufficient to make waves in the pool and cause water to go overboard.
Is it normal to use this much MA?
My latest test results
CYA-40 (recently added stabilizer so I expect this to go up)
This summer I will be adding a SWCG and will be adding salt soon. What effect does a SWCG have on pH if any? Would I benefit from the use of borates?
