CALCIUM HARDNESS
Calcium hardness affects pool water quality. Low calcium hardness can
promote pool corrosion. High calcium hardness can cause cloudiness.
Ideal calcium hardness content is 400 ppm as measured by a suitable
kit. The ECOsmarte Pool System will eliminate scaling in your pipes.
Calcium hardness will need to be tested at start-up and if the pool is
refilled. It should also be tested after extended days of heavy rain.
ECOsmarte has many pools at 800 to 1000 ppm calcium hardness, and
draining back is recommended at 2200-2900 ppm.
POOL STORE COMPUTERS: pH, CALCIUM & PHOSPHATES
Can be a useful tool to double check your pH and calcium hardness. Do
not however adjust alkalinity or copper based on the results. Alkalinity
should be adjusted upward if the pool is crystal clear and "grass green"
or "lime green" in color. Rely only on the Lamotte Copper test kit included
with your ECOsmarte System to use the IONIZE mode and add copper
to the pool.
PHOSPHATES: Must be confirmed at ZERO once per year.
• For a reduction in Total Alkalinity experts recommend
"pooling" the acid in a small area of low current.
Normally, ECOsmarte Pools need no downward alka-
linity adjustment.
• Upward alkalinity adjustments should be done in 4lbs
increments per day of sodium bicarbonate. Any more
and "pH bounce" may result, causing you to waste
time and money on acid. Do NOT raise Alkalinity
unless water is clear lime green, (or "grass green but
clear.'') - Adjust no higher than 80 ppm.
• Upward alkalinity adjustments can be made with
sodium bicarbonate, baking soda or any brand of alka-
linity enhancer. We recommend 4lbs max per day and
DO NOT OVER ADJUST.
• For a reduction in pH, walk acid around the pool and
distribute it to the entire pool, having diluted the acid
with water in a 5 gallon bucket.
