Frequently Asked Question's

 

How do I know how many gallons of water are in my pool?
To determine the total gallons of your pool, follow these simple equations:
Rectangular pool
Length X Width X Average Depth X 7.5
= total Gals
  Round Pool, oval pool, free form pool
Diameter X Diameter X Average Depth X 5.9
= total Gals
Why is controlling my pool’s pH so important ?
ANS: pH is the measure of alkalinity or acidity in your
pool. Pools with unbalanced pH levels are un-
comfortable for bathers and can cause eye irritations,
skin discomfort, and hair and bathing suit bleaching.
Too much acidity in a pool is corrosive to metal fixtures.
Too much alkalinity in a pool causes “scales” to adhere
to metal fixtures and reduces the effectiveness of chlorine.
In addition, pH levels out of the accepted range renders your sanitizer to be less effective.
What are the acceptable ranges for pool water?
Chlorine (free) -  1.0 to 1.5 ppm
Combined chlorine - < 0.5 ppm
Bromine (spa) -  2.5 - 4.0 ppm
pH: -  7.4 to 7.6
Total alkalinity: -  120 to 150 ppm
Calcium hardness: -  120 - 150 ppm (vinyl) 250 ppm (gunite)
Cyanuric acid (chlorine stabilizer): -  40 - 60 ppm
Iron and copper: -  "0" ppm
Total Hardness: - < 2000 ppm
