I have a aqua rite chlorine generator AQR15 and flow switch went bad. Pool starting turning green. Went to pool store and the told me to add 4 gal of liquid shock till a get a flow switch.. Did that and the green in the pool stared looking better and pool looks good now within about 8 hrs. Orderd new flow switch got it overnight Replace flow switch and put it on super chlorinate . Check it about 8 more hrs and and pool shows chlorine @ 1500. Added a bag of salt Checked it this morning and showing 1200. But light on aqua rite say needs salt and check cell. Did that and cleaned, which cell looked good. I have a in ground pool 16x32...3ft to 5ft deep. Could cell went bad to. Only had aqua rite for two years. Thanks
