Things went well under my dome this past winter but as soon as I removed it and tried to start up the swg again it's lights went on for awhile but then out. I checked for deposits on plates and they are clean as new, had electrician check the power in the box and its all good so I believe since it was put in in 2012 it has met its life expectancy even though I would have liked to get another year out of it. Ordered new one and have been pouring in the bleach almost every day, working on getting cya up to summer level and trying to keep ph down. I admit I have not given it my all but checking fc and ph every few days or so, while trying to work out the swg problem. New one arrives and instuctions say Before Installing Balance pool water to PH 7.2-7.8, CH 200-400, alk 80-120, Superchlorinate the pool set stabilizer to 30-50ppm Ensure no phosphates or nitrates in pool set salt to 3200-3400ppm. So there's that nasty word "phosphates" So I do my own full testing with my TF-100 kit and I get fc 0 tc 0 (it's very hot here in OK) ph 7.8 ch 240 alk 60 cya 60 and remembering something on here about phosphates I decided to send hubby to the dreaded pool store to get full testing and with strict instructions not to buy anything! their results are FC 0 tc 0 salt 2700 ch 240 cya 60 alk 60 ph 8 and the nasty posphates 1000! So before doing anything I come here to jog my memory about them and after reading some forums I know why I have not worried about them before but now I'm concerned about putting in the new swg and am wondering in what order I should do my balancing and how long to wait between each and when done should I still not worry about phosphates and go ahead and install new swg? Water is not green but slightly cloudy and I do believe I see tiny spots of algae begining on steps. Thanks for any help
