Basic Water Chemistry - E4aqua:
CAUTION !
Excessively high chlorine levels can cause premature cell failure and corrosion damage to pool
fixtures and equipment.
CAUTION !
Always follow the instructions on the manufacturer's label whenever handling or using chemicals.

EFFECT OF LOW/HIGH LEVELS
SCHEDULE
Weekly
Low free chlorine: Not enough residual
chlorine to safely sanitize pool water.
High free chlorine: Corrosive to metallic
fixtures in pool water. Can bleach
swimwear and hair.
Prior to
Low pH: (acidic) Equipment corrosion,
swimming
eye/skin irritation, plaster etching, rapid
every few
chlorine consumption
days
High pH: (basic) Scale formation, cloudy
water, eye/skin irritation, poor chlorine
effectiveness
Monthly
Low TA: Eye irritation, pH "bounce",
stained/etched plaster and metal corrosion.
High TA: Some difficulty in maintaining Ph.
Monthly
Low Salt: Below 3 mS leads to insufficient
power to the cell. May read "Check/clean
cell" Salt less than 750 ppm may decrease
chlorine production efficiency.
High Salt: Above 4.0 mS leads to
inefficiency of chlorine production. Salt
greater than 1500 ppm may encourage
corrusion of pool parts.
Monthly
Low CH: Etching of plaster, equipment
corrosion
High CH: Scale formation, cloudy water.
Rapid buildup of scale may exceed the
system's self-cleaning capability and require
manual cleaning of the SuperCell.
Monthly
Low CYA: Destruction of chlorine by the UV
rays from the sun.
High CYA: Requires more chlorine to
maintain proper sanitizer levels. Note: CYA
not needed for indoor or bromine pools.
CORRECTIVE ACTIONS
Low free chlorine: Check for combined
chlorine level and shock if necessary.
Increase purifier output to maintain a 1-3
ppm residual reading.
High free chlorine: Decrease purifier output.
Let chlorine dissipate normally until 1-3 ppm
is achieved. In extreme cases, pool water
can be diluted with fresh water or a chlorine
neutralizer added. (Diluting will reduce salt
and CYA. Check and adjust as needed.)
Low pH: Add sodium bicarbonate
High pH: Add sodium bisulfate.
Low TA: Add sodium bicarbonate.
High TA: Add sodium bisulfate to correct for
pH. Do not add muriatic acid. Do not add
sodium bisulfate to a point where the pH
drops below 7.2.
Low Salt: Add E4aqua by whole bag
increments if the conductivity is low. If only
Salt levels are low, adjust to 1000 ppm with
pool salt only.
High Salt: If the conductivity and/or salt
levels are high, partially drain the pool and
refill with fresh water to aappropriate levels.
If the conductivity lowers to appropriate
levels and the salt is loo low, add pool salt
appropriately.
Low CH: Add calcium chloride flakes.
High CH: Partially drain and refill pool with
fresh water to dilute. (Diluting will reduce
salt and CYA. Check and adjust as
needed.)
Low CYA: Add cyanuric acid(1 lb/5000
gallons increases CYA 25 ppm)
High CYA: Partially drain and refill pool with
fresh water to dilute. (Diluting will reduce
salt. Check and adjust as needed.)
