Use the calculations below to calculate the setting for Ion/Action and Large Dose based on your
ClearBlue model and pool or spa volume. The Ion/Action and Large Dose can be set to the same
value.
Use the Large Dose Function as many times as needed until the copper level reaches 0.2ppm.
Set the Ion/Action setting first, then set the Large Dose. The Large Dose timer will count down and
then switch automatically back to the Ion/Action setting.
The setting calculations are guidelines only. You must use a copper test and increase or decrease
the Ion/Action setting as required to ensure the copper level is maintained at 0.2ppm to 0.4ppm.
DO NOT REDUCE CHLORINE/BROMINE CONCENTRATION UNTIL COPPER LEVEL REACHES 0.2PPM
Calculating Pool Volume
The ClearBlue controller settings are based on the volume of water in your pool or hot tub. Please use
the calculations below to determine your water volume.
Pool Type
Calculation (Using Feet & Gallons)
Example
Rectangle
Length x Width x Avg. Depth x 7.5 = Volume (gal)
16 ft x 32 ft x 4 ft deep, 8 ft deep end
16 x 32 x 6 x 7.5 = 23,040 gal
Circle
Diameter x Diameter x Avg Depth x 5.9 = Volume (gal)
24ft round pool x 4ft deep
24 x 24 x 4 x 5.9 = 13,594 gal
Oval
Long Dia. x Short Dia. x Avg Depth x 5.5 = Volume (gal)
18ft x 33ft oval pool x 4ft deep
33 x 18 x 4 x 5.5 = 13,068 gal
Irregular Shape
Length x (Width 1 + Width 2) x 0.45 x Avg Depth x 7.5
= Volume (gal)
16 ft long 5 ft deep kidney pool
16 x (8 + 10) x 0.45 x 5 x 7.5 = 4860 gal
Average Depth
𝑫𝒆𝒆𝒑 𝑬𝒏𝒅 𝑫𝒆𝒑𝒕𝒉 + 𝑺𝒉𝒂𝒍𝒍𝒐𝒘 𝑬𝒏𝒅 𝑫𝒆𝒑𝒕𝒉
𝟐
4ft deep pool with 8ft deep end
8 + 4
2
= 6
Meters to Feet
𝐋𝐞𝐧𝐠𝐭𝐡 𝐢𝐧 𝐌𝐞𝐭𝐞𝐫𝐬 𝐱 𝟑. 𝟐𝟖𝟏 = 𝐋𝐞𝐧𝐠𝐭𝐡 𝐢𝐧 𝐅𝐞𝐞𝐭
10 meter long pool in feet
10 x 3.281 = 32.81 ft
