ADD WATER TO CHEMICALS
Adding bromine to a pool or spa lowers pH
, Adding chlorine to the pool to the pool raises the pH
Algae forms because of poor circulation and/or low chlorine levels
As the dirt in the filter accumulates the decreases while filter pressure increases
flow of water going through the filter
Breakeven point level of chlorine at a 10 times the level of chloramines
pool you must have
CDC states that the number of accidents 140,000
related to swimming are:
over the course of time the filter and sand is bad and deep channels are formed
Channeling means
in the sand causing it to filter poorly
Electrical system at pool must have GFI's
Filtration is the physical process of water moving through the system.
The flow of water through the filter is gallons per minute
Flow Rate= Turnover Rate/Filter Media Rate
number of gallons divided by hours of turnover (multiply hours by 60 to get
Flow Rate=
minutes)
The formula for area is length x width
