Yeah read your FAQ which is great, and I have called 3 welding supply shops within 10 miles of my home, they all want $60 for a lb steel tank, empty!
I'm wondering where others in the bay area get there tanks, the bay is so huge, that it is quite possible that there is a great place that charges less. That might not be that far away.
29 Gallon Standard Moderate Light Planted tank
Lighting: 2x27 Watt 6500k P.C. Lights of America Outdoor Fixtures. 2x 20 Watt N.O. Flor. w/ Sylvania Gro Bulbs (9350k I think). Both are retrofited into a diy 12" tall canopy, with a 4" Diameter Clip on fan facing the opening in the back to circulate the excessive heat from the lighting.
Filtration: Tetra Tech 150 (modified to make very little disturbance.
Aquarium Systems Mini-jet for more circulation.
