Bringing an oldie back to the top!!!!

Ive been using the Eclipse ozone generator on the pool and a smaller ozone generator on the spa and its worked great so far(I guess its been about 13-14 months).

Ive been keeping track of my chroline usage and in that time period for the pool and the spa I have used ~38 lb of 3" chlorine tablets, about 6 gallons of muriatic acid, and about 5 jugs of the liquid chlorine (I dump some liquid in every so often just for yucks).

Is this a normal amount of usage for an ~18,000 gallon pool and ~600 gallon spa in FL? The pool gets used year round, but in Jan/Feb use is alot lighter as even with the solar the temp hangs in the 70-75F range and we are wimps.
