I completely agree, the color temperature of the bulb probably is not the best choice. But, with the 20K bulbs I do enjoy it MUCH more. I have looked around for the "right" tub. I have some that are RubberMaid brand and they are no where near the quality of the tubs I got from Orscheln's Farm Store. Much thicker fiberglass/plastic and much cheaper. $149.00 for 300 gallons, cant beat that!
