It looks good Badflash! The storage barrels will also need to be black to stop algea growth. I did the same thing with (3) 300 gal. totes. I use them for a thermo sink and emergency backup water. I'm on well water and don't want to pull to much at one time. When I first started I met a fish raiser in Cleveland. He had city water. He kept an extra tank of water and aerated it to get rid of chlorine and told me to always keep enough water to fill a tank in case of emergence.
