Filters are necessary to remove particles of dust, dirt, algae, etc.
that are continuously entering the water. If the spa is not operated long
enough each day for the filter to do a proper job, this puts a burden on the
chemicals, causing extra expense. Filtration time will depend on the spa size
pump and filter size, and of course, bather load. A spare cartridge should be
kept on hand to make it easy to frequently clean the cartridge with out the
need for a long shut down. This will also allow the cartridge to dry out
between usages, which will increase the cartridge life span as much as twice.
Replace the cartridge when the pleats begin to deteriorate. Cartridge
cleaning should be done a minimum of once a month. More often with a
heavy bather load.
This is what kills the germs and bacteria that enter the water from
the environment and the human body.
A. Chlorine
1. Only one type is good for spa use
a. Sodium dichlor which is a granule, fast disolving,
and pH neutral
2. Chlorine is an immediate sanitizer.
B. Bromine (Note: Bromine use is not recommended with Eco Pur filters.)
1.Two types of tablets.
a. Hydrotech
b. Lonza
2. Bromine is a slow dissolve chemical and may take a few days to
develop a reserve or reading in the water.
i.e. Like what happens when you put sugar in coffee or tea.
days):Water should be drained at least once every
180 days. Useful life may vary by usage and bather load.
Foaming may be caused by body oils, cosmetics, lotions, surface
cleaners, high pH or algeacides as well as other organic materials. Low levels
of calcium or sanitizer can also cause foaming. Also, double rinse your
bathing suits as they will hold residual soap after being washed.
Water that is too hard (over 250 ppm) can promote scale
formation in components and on spa surface. Water that is too low
(below 180 ppm) may also shorten the life of metal components on the spa.
