Coloured
Water/Metals
Copper
may erode or corrode from the spa's circulation system and dissolve
into the water due to high velocity and/or low pH, low total alkalinity
and low calcium hardness. This can show up as green or greenish-blue
water. The source or make-up water may also contain metals such as iron,
copper or manganese. To prevent these from depositing out on the spa's
surface and causing ugly stains, use SpaGuard® Stain and Scale Control.
A metal remover such as BioGuard® Quick Clear can help remove most
common metals from solution in spa water. In instances where dissolved
metals are suspected or detected by your Water Wizards SpaGuard Specialist,
it may be necessary to drain the spa and refill with fresh water. If
that's the case, be sure to follow proper start-up procedures and testing.
Stains
Stains
are usually caused by metal in the water as listed above. SpaGuard®
Stain and Scale Control may lighten or remove fresh stains. Prevent
stains before they occur by adding SpaGuard® Stain and Scale Control
weekly.
Scale
Rough,
sandpaper-like deposits can coat spa walls, clog circulation and filtration
systems and plug heaters. Scale is a result of excess dissolved calcium
in the water. It becomes unstable in solution because of high pH in
hot water and precipitates out as calcium carbonate. Use SpaGuard®
Stain and Scale Control on a weekly basis to prevent scaling and cloudy
water. Maintain pH between 7.2 and 7.6; total alkalinity between 125
and 150 ppm; and calcium hardness between 100 and 200 ppm. To test the
levels, use the 4-way test strip or take a water sample to your Water
Wizards SpaGuard Specialist every 4 to 6 weeks for an analysis.
Foaming
High aeration
and agitation combined with body oils, lotions and high temperatures
will sometimes create an undesirable foam level. SpaGuard® Anti
Foam Concentrate stops "foam" almost immediately.
Cloudy
Water
Cloudy
water may be due to heavy usage of the spa or hot tub or the initial
bleeding of tannin from wood surfaces of hot tubs. Sometimes bathers
add particulate matter too small to be removed from by the filtration
system. SpaGuard® Polysheen collects these small particles into
larger ones that can be filtered out - leaving sparkling clear water.
SpaGuard® Polysheen is ideal for regular use to improve water quality.
Irritations
to Eyes and Skin
As the
spa is used, non-filterable wastes such as perspiration, oils, hair
sprays, cosmetics and body fats can accumulate. This makes the water
dull, irritating and unattractive, as well as interfering with sanitiser
activity. To remove these wastes and restore sparkle to the water add
50 grams of SpaGuard® Chlorinated Concentrate per 1000 litres of
spa water once weekly when the spa is not in use. An alternative would
be to use SpaGuard® Brominating Concentrate.
IMPORTANT:
Leave the spa cover off for at least 1 hour after the addition and run
the pump to circulate the water.
