Would suggest you get more and larger tanks to get you from summer to summer. When I built the new house, I bought two 1,000 gal tanks, that I own. Not hard to figure usage VS capacity and that a summer buy is cheaper per gal than the winter buy. Plus buying at 800+ gal increments is cheaper per gal.
