thanks for getting back Ben, after adding 2 gallons CH, I'm seeing 2.3 on the CH..... 7.4 on ph .....100 alky..I added 1 more gallon of CH. My cya still read ,<30 no prob. CH is coming up, I'm watching it....No fun though....I swept the pool for 2 hours yesterday and got IN the pool and while there swept for 3 more. Question .....when you sweep is it necessary to get ALL the light green off before filtration takes over? Found out while being in the pool my Barracuda MX8 for the second time quit running...gears must be shot again I don't know what other sweeps might be better or maybe just do it by hand. Thanks again...Dave
