Corrosion of Copper |
|
Adjust
pH, shock treat with shock treatment. Repeat if
Necessary. Follow remedies for colored water and
corrosion of metal parts. |

|
|
|
|
|
|
| Corrosion
of Metal Parts |
|
Metal
fixtures in contact with pool water being eaten
away; rust stains; copper stains; colored water |
|
Low pH
and or Low Alkalinity and or Low Calcium
hardness. |
|
Adjust pH
to 7.2 - 7.6 by adding pH plus. Raise alkalinity
to 60-100 ppm if using granular and 90-125 ppm if
using chlorine tablets or sticks. Raise calcium
hardness to a minimum of 200 ppm by adding
calcium plus. FOLLOW LABEL INSTRUCTIONS |

|
| Chlorine
Odor |
|
Swimmers,
eyes become irritated, water has an unpleasent
odor, complaints of to much chlorine in water. |
|
Chlormines
formed by reaction with bathers waste. |
|
Adjust pH
to 7.2 - 7.4 shock treatment. Repeat if
Necessary. |
| |
|
|
|
|
|
|
| Eye
and Skin Irritation |
|
Red eyes,
itching eyes |
|
Chlormines
(see chlorine odor) improper pH |
|
Adjust
pH, shock treat with shock treatment. Re-adjust
pH with pH plus (soda ash) or pH minus (dry acid)
or muriatic acid to 7.2 - 7.6 range. |
| |
|
|
|
|
|
|
| Algae |
|
Green or
brown algae turn water green, pool surfaces feel
slippery, can also cause cloudy water. Black
algae forms patches on pool sides, giving them a
spotty look. |
|
Insufficient
Chlorine. High stablizer level. Improper pH |
|
Adjust
pH, shock treat with shock treatment. Vinyl
liner: Use soft nylon brush. Repeat if necessary.
Add algaecide. Follow dosage recommended on
label. |
| |
|
|
|
|
|
|
| Scale
Formation |
|
Scale on
pool wals and fixtures. Frequent in new inground
pools. |
|
High pH,
excess alkalinity. Excess calcium hardness |
|
Reduse pH
to 7.2 - 7.6 with pH minus or muriatic acid. Use
pH minus to reduce total alkalinity to 60-100 ppm
if using chlorine granular. 90-125 ppm if using
chlorine tablets or sticks depending on pH and
calcium hardness. Lower calcium hardness if
necessary by draining water and replacing it with
water having a lower hardness. |

|
| Colored
Water |
|
Brown,
Black, Blue-green water |
|
Iron,
Manganese, copper in excess |
|
Shock
treat with shock treatment. Floc pool or sand
filter with alum (not recommended for DE or
cartridge filters). Follow remedy for corrosion
of metal parts. To prevent colored water use
stain and scale controller. Follow Instructions. |
| |
|
|
|
|
|
|
| Excessive
Available Chlorine |
|
Bleached
hair and bathing suits. Possible eye irritation. |
|
Excess
Chlorine |
|
Add
sodium sulfite or sodium bisulfite or sodium
thiosulfite. |
| |
|
|
|
|
|
|
| Cloudy
Water |
|
Hazy,
cloudy water, lack of sparkle. |
|
Early
algae growth. Pool filtration, High pH, high
alkalinity |
|
Adjust pH
to 7.2 - 7.4 shock treatment. Check filter
operation. Re-adjust pH with pH minus or muriatic
acid to 7.2 - 7.6. Add clarifier to aid filter in
removal of fine suspended particles.Follow
Instructions. |
