cleaning my pool that is. I leave for Mexico two weeks and come back to a once crystal blue swimming pool to a purple tint on the wall, floor and cleaning hose. Apparently since my pool pump was off and alot of rain came when I was gone it created a purple tint. Did some research to find out the water has magnesium which create the purple. I guess $80 will be added to my monthly bill for a pool cleaner. Never ends people!
