Magnapool® FAQs

Got a Question?

See below for answers to some of our most frequently asked questions regarding MagnaPool®. If you can't find your answer here than please contact us.

The MagnaPool® Minerals in the bags have clumped together into a solid block, can I still use them?

This usually indicates the minerals have been exposed to air and moisture. The minerals are still good to be used but will take longer to dissolve. Be sure to monitor and brush minerals around the pool as they dissolve. 

There is white froth on the water surface after adding the minerals. What should I do?

This is normal during the start-up process as the minerals reach equilibrium with the water. It will usually dissipate within a few hours or sometimes overnight with the pump running.

After adding minerals I’ve noticed a yellowish discolouration on the pool floor. What should I do?

This can be caused by a concentration of minerals that have settled on the bottom of your pool due to insufficient circulation after dosing the minerals. It is recommended to leave pumps running overnight to evenly distribute the minerals. If the discolouration remains, try using Zodiac’s ‘All in one stain remover’.

I cannot detect chlorine in my pool after adding minerals. What should I do?

Most testing equipment cannot detect chlorine levels accurately due to so much activity occuring in the water during this process. Chlorine is present and effective, so simply leave the Hydroxinator on ‘boost’ mode overnight and you will find that within a few days (possibly up to a week) you’ll be able to detect the sanitiser levels. Please note: even though sanitiser levels are not detectable, the water is still safe to swim in.

There is white residue occurring at the waterline or in the pool. What should I do?

There is white residue occurring at the waterline or in the pool. What should I do?
Check that the water chemistry is balanced by paying particular attention to your pH and Hardness levels. Magnesium will interfere with Total Hardness tests so ensure your mineral levels are correct, and add more minerals as required.

Are there any products incompatible with MagnaPool®?

If granular chlorine is required at all, use Calcium Hypochlorite (Zodiac Pool Chlorine) instead of Dichloroisocyanurate (Zodiac Pool Purifier) as this can cause a discolouration in the water.

Why do I have to add more bags of MagnaPool® Minerals compared to traditional salt?

Magnapool Minerals are not chemically equivalent to traditional salt. The hygroscopic nature of Magnesium chloride means that when it is added to the pool, it doesn’t deliver the same level of salinity. Whereas salt delivers 1:1 ratio of salinity, magnesium delivers only 0.7:1, therefore more is required.
