Summary of Water Chemistry Parameters
10.1.
The table below is a concise set of readings that should be maintained during
the course of the year. If these parameters are met you will be assured of a
Sparkling Clear Pool all year round. Remember, your pools appearance is directly
proportional to your interest and effort you afford it.
10.2.
There are a number of excellent websites that will enlighten you in
“Swimming Pool Water Chemistry” should you wish to further your knowledge on
water chemistry. Alternatively make use of our own website:

.
10.3.
Here are the Parameters that should be noted and adhered to:
•
Chlorine level - 1.5 to 3.0ppm
•
Salt level - 0.6% - 6000ppm non iodised salt
•
pH 7.2 (Marbelite pools), pH 7.0 to 7.2 (Fiberglass & painted pools)
•
Total alkalinity 80 to 140 (Marbelite pools), 120 to 150 (Fiberglass & painted
pools)
•
Stabiliser 40ppm to 60ppm (have tested before adjusting)
•
Metals and copper - Zero
•
Calcium less than 200ppm
10.4.
It is recommended that you invest in a 4-in-1 water test kit from your local
pool dealer, or retail outlet for easy pool water testing.
•
Never add stabiliser to your pool without first having the water tested for
stabiliser by a reputable pool shop.
•
Over stabilizing effectively “locks” the chlorine rendering it ineffective as a
sanitizer. Never stabilise a green pool. Fix it first.
•
In the case of over-stabilisation one would have to “dump water” and add
fresh water, this effectively dilutes the Stabiliser allowing the chlorine to
sanitise.
11. Metal and Copper
•
Any metals present in the pool water spells doom for the chlorinators
electrode. These metals, due to the salt water electrolysis process, will
impact on the electrode causing premature failure.
•
Not only will the electrode fail prematurely, but staining of the pool surface
may occur.
•
There are a number of Pool Service companies that are able to remedy this
situation; this entails the draining of the pool water and the acid washing of
the pool surface. This tends to be a costly exercise for the pool owner.
•
It is therefore recommended that prevention is better than the cure in this
instance. It is highly recommended, that you as the pool owner, apply a well
known brand of “Metal Remover” to remove any waterborne metals from
your pool water.
Remember, when adding any chemical, especially Metal Remover, the chlorinator must be
TURNED OFF. Only once the metals residue has been vacuumed too waste, can the
chlorinator be switched back ON.
NOTE:
Copper (Cu) can only enter the pool by the hand of the owner, beware that
same hand may smack you later. Always ask the supplier if the product you are
buying contains Copper (Cu) if it does.... don’t buy it!
12. Calcium
Most pool shops can test for calcium levels.
12.1.
The higher the calcium level in your water, the more frequently you will need to
clean the chlorinators’ electrode.
