Unfortunately its time to close the pool.  I have previously blogged about salt Chlorine Generator and now is the perfect time to install one if your thinking about it.  If your not you should because its the best system around and its all the rage for a reason.  Being the end of the season you can save a few bucks now on them and be ready for next year.  A friend of mine just got the Blue Essence Salt Chlorine Generator and save $150 from Dohenys Water Warehouse.  Also check your water tube bags.  I always seem to need a few every year.  Dohenys is having a great fall sale, and all pool winterizing supplies are on sale.  Check out Dohenys fall sale and get free shipping coupon.
