What is the difference between a MagnaPool and a normal pool?
A MagnaPool is an environmentally friendly alternative to standard swimming pool salt that uses a unique blend of minerals. All pool water parameters such as total alkalinity, cyanuric acid, etc are as normal. Calcium hardness is as per the instructions given for the interior finish of the pool.
In times of water shortages or whenever a pool is filled from tanks, bores or streams a phosphate test must be done.
*NB - AT PRESENT MAGNAPOOL RECOMMEND A PHOSPHATE TEST IS DONE DURING EVERY WATER TEST AND ESPECIALLY ON START UP.
How do I test for MagnaPool Minerals?
MagnaPool Minerals can be tested by means of a standard NaCl conductivity meter and is accurate to about +/- 4%.
What Mineral concentration level does a MagnaPool run at?
MagnaPool recommend Mineral concentration level of 3000ppm, however individual circumstances can dictate running a system with a higher or lower salt level. The recommended minimum is 3000ppm and maximum is 6000ppm.
As a pool shop what test should I use when finding the water hardness level of a customer MagnaPool sample?
You should perform a Calcium Harness Test. Calcium is the appropriate element to test for in pools because the correct calcium hardness is needed to protect the pool finish and is a contributing factor in scaling (calcium deposits). A Total Hardness Test will register Magnesium Chloride (the active ingredient in a MagnaPool) as well as the Calcium content, so the results of this test will read abnormally high. A Total Hardness Test is meant for applications such as boiler water and other industrial applications.
What are the recommended pool chemistry limits for a MagnaPool?
The pool chemistry requirements for the MagnaPool system are those indicated within the Australian Standard ‘Optimum Range’ (see the tables below). The Australian Standard (AS3633-1989 – Private Swimming Pool – Water Quality) is available through your local pool shop.
