Calcium Hardness_When to drain and when not??
I just got a calcium hardness test at my local Leslie pool store and its 575ppm
They told me a month ago to drain my pool ( but not how much)
We have just had a ton of rain over the last 4 weeks and i was going to drain my pool today but thought to get a new test.
There test states ideal range of 200-400ppm and not to drain water from pool till it hits about 1,000ppm.
Now my buddy has his local pool store computerized readout stating ideal is 175-225ppm
Whats the correct amount?
My pool is 28,000 gallon. How many gallons should i drain to get to the sesired level.
Keeping in mind that our supply water is considered high in calcium.
