Well, its still on the low side, 24 watts over 15 gallons is still less than 2 wpg. But its definately better than 18w!

Would putting tinfoil behind the bulb help it out any???

No, tinfoil is less reflective than some bright white spray paint, and by a good margin. Mylar is much better than either, just use the inside of a mylar balloon, rubber cemented to cardboard. Remember to give the cardboard its final curvature BEFORE gluing the mylar, or the mylar will wrinkle more and loose some reflective potential.

cool thanks
