To remove stains from the pool surface drain and acid wash the pool
Adding chlorine to the pool to the pool raises the pH
Adding bromine to a pool or spa lowers pH
The formula for area is length x width
formula volume is length x width by depth by 7.48 (num. x num. x num. x 7.48)
To measure the area for circular pool 3.14 r^2
Flow Rate= Turnover Rate/Filter Media Rate
Flow Rate= number of gallons divided by hours of turnover (multiply hours by 60 to get
minutes)
, CDC states that the number of accidents related to swimming are: 140,000
Minimum number of ladders required in a pool are: 2
Stairs in a pool must be accompanied by a handrail must be anchored in the pool deck and
in the bottom step
When a pool has deep water more than 5 feet must have a safety line and a slope line

Channeling means over the course of time the filter and sand is bad and deep channels are
formed in the sand causing it to filter poorly
As the dirt in the filter accumulates the flow of water going through the filter decreases
while filter pressure increases
removing dirt/particles from filter backwashing
High speed sand filters are able to filter how much water per minute per square foot? 15-
20
The flow of water through the filter is gallons per minute
