I just tested everthing I can test.
Water Temp. 92 deg. * PH 6.7 * Total Alk. 180-200 * Total Chlorine .05 * Total Hardness 980-1000. Thats all I can test with my kit. Yesterday morning I put in 1 full gallon of Muriatic Pool Acid, (which brought the PH down from 7.8) and 1 full quart of AquaChem Metal Stain and Scale Out (available at Lowes) and ran the filter straight 24 hrs. Water is crystal clear, except for the stained hairline cracks. Oh by the way I did not mention-I have a cartridge filter, and and chlorine puck auto feeder. Also the water level is automatically kept up to proper levels with softened water. I wish I could post a picture of the bottom of this pool. Thanks Again All !!
