We've tried everything ...we just bought an above ground Intek 14x4 foot round pool/filter 635r on 6-21-12.it was crystal clear when we filled it with well water ,it wasn't until the pool place had me start adding chemicals that it turned green.they had me put in 2chorine tablets in a floater then alkalinity plus that's when i noticed it changed to green that was on 6-26-12.they had us wait they were concerned about minerals in our well water but it never showed up on the test. they said on 6-27 to add mineral out to cover the bases they thought it could Be to high to show,they did check for magnesium he said that was high so i had to add all of 16ounce bottle,next day or so noticed brown clumps on bottom of pool they said it was working.on 6-28 my husband shocked the pool,on 6-29 added calcium hardness and today finally added stabilizer ,pool is still green ..we really want to swim in it, they said its fine to since the numbers are good but I'm concerned,please help...our pool numbers are as of 6-30-12 free chlorine -6.7,total chlorine -6.7 but is back to normal range now,combined chlorine-0.0,ph-7.5,hardness-250,alkalinity(with stabilizer correction)cya-10,copper-0,iron-0..chemicals were using glb brand..
