For this you should first get the pool water tested by a lab in pool store.
How to remove iron from well water in pool.
Follow the processes below to use this method.
To remove iron and other metals from water you have many solutions but you should choose the right method only after analysing your pool.
Let s discuss about some of the commonly used iron removal methods in detail.
If your well needs to be treated for arsenic and iron traces choose an oxidation system to filter your water.
This will oxidise the iron and most likely the taninn and will form a precipitate which will settle.
One way that might be successful which will remove the iron as well is to dose with calcium or sodium hypochlorite.
This method works by adding flocculent a woolly substance to the water to collect the iron and settle it at the bottom of the water.
Oxidation filters are generally stronger than water softeners and can remove harmful chemicals that are common to well water specifically arsenic.
The brown stain might be caused by the ioniser that deposits iron metal in your pool you need to clear the stains using ascorbic acid then consider reducing iron metal levels in your pool by draining and refilling a portion of your pool water or use a metal remover such as proteam metal magic to remove metals through the filter and avoid brown stains when you shock your pool or when ph is low.
Here in the algarve we have the same problem with borehole water but we do the following shock the pool to oxidise the iron out of solution and into floating sediment then add flocculant to cause all the particles to lump together and sink to the bottom this we do with the pump off at night as the sun causes currents that disturb the settling process.
Shock treat the pool.
After they confirm the high levels of iron in your pool water you can take their guidance for solution.
Methods to eliminate iron from pool water.
The idea of aeration to remove iron from water from a borehole or well water is to allow the water to mix with air.
Aeration brings water and air into close contact in order to oxidize the iron and bring it out of solution form to solid state.
