How to Convert Saltwater Pools to Mineral Pools

Do you own a saltwater or chlorine pool and want to convert to a MagnaPool? It is possible to experience the difference with a few tweaks to your pool. 

It is recommended that you carry out a full water analysis prior to converting your pool to ensure everything goes smoothly. There are 3 major components make up the MagnaPool system, each element offers its own benefits, but when all three are combined, the result is truly amazing.

• The Hydroxinator & Reverse Polarity Electrolytic Cell
• Glass Filtration Media 
• and, of course, MagnaPool Minerals 

Below you'll find step-by-step instructions on what you need to do in order to convert your saltwater pool into a MagnaPool®. If you have difficulty performing any of these tasks, use our locator tool to find your nearest MagnaPool® specialist, who will be able to assist you. Alternatively, you can reach out to us via our MagnaPool Facebook page if you need recommendations for a pool professional.

1. Replace your chlorinator with a Hydroxinator

Fit the Hydroxinator in a suitable spot and connect the electrolytic cell on the plumbing line. Any reputable pool care professional can do this and it’s relatively inexpensive. We highly recommend that you use a hydroxinator as it has been specifically matched to MagnaPool minerals and will ensure our customer care team provide you with top quality service and assists in diagnosing any issues should they arise.

2. Empty out media from the filter if using sand and fill with glass media. 

Removing the sand from a filter will require a specialist and any reputable pool care professional can assist you. Once the filter is empty of sand the glass media can be loaded. Using coarse glass on the bottom of the filter (just enough to cover the laterals is sufficient) and then the rest is filled with fine glass. This combination of coarse and fine allows for the best filtration and backwashing capabilities. Note that a cartridge filter can be used, but it will need to be a largely oversized model to help prevent excessive cleaning due to the exceptional flocculent properties of MagnaPool minerals. However the preferred method is to use a media filter filled with glass.

Note: On some pools you may only be able to use a cartridge filter, in these cases it may be necessary to move up to a larger size, or additional cleaning of the filter elements will be required. To ensure smooth ongoing operation we highly recommend that a larger cartridge filter is installed, speak to your local pool care professional about your options. 

3. Get a TDS test done as you may need to remove some water from your pool.

Your TDS will need to come down to at least 1,500ppm before you can add in the appropriate amount of minerals. Most saltwater pools will have a TDS of around 4,500-5,000ppm, so if you have a TDS of 4,500ppm you will need to remove 2/3rds of the pool water first, then refill with fresh water. If you have a TDS higher than 4,500ppm, it is recommended you drain your pool entirely, and then refill it with fresh water. Please note that draining your pool is a delicate process due to hydrostatic pop, which can damage your pool shell. This process will require special assistance from a reputable pool builder. Get a salinity and/or TDS test is done to determine how many bags of minerals need to be added to your pool. 

4. Add in minerals.

Based upon the above measurements, you simply need to add in the appropriate amount of minerals and switch on your filtration equipment. Use our Quick Calculator tool below to determine how many bags of MagnaPool® minerals you will need. Usually, it is around 3-4 bags per 10,000 litres.

5. Turn on the system and run for 24hrs

Once you’ve added the right amount of MagnaPool® minerals, let the system run for at least 24hrs non-stop to get proper circulation and dilution, just press Boost on your Hydroxinator for this feature. You may notice some foaming appear during this start-up phase, this is part of the process. After 24hrs has passed you can jump in and start enjoying your new MagnaPool®!
