First thanks for reading my post. I am new to pool. I have salt water kidney shape pool. Last year we used a service to close the pool, this time I have put everything in place and started the pool. When i open the pool, it was dark green, searched online and found time to shock it.. i added 7 gl shock to pool and let it run for about 48 hours. The pool still looks cloudy but not that much green. I have electronic chlorine generator (Swimplus), the reading shows zero and no flow light stays on.. i tried to unplug and try setting didn't work.. my question is what do i need to do next? all levels are low at the moment. when do i add salt? PH? other things for the pool so it became crystal clear. and what could be wrong with reading box? please advice.
