I took an in-person trip to Home Depot, and an online visit to Lowes, and I could find neither an 18" shoplight, nor a ballast that supports 18" bulbs. Is there any way I can rig a ballast rated for 2' bulbs with 18" bulbs, or should I just order slimpaqs?
The slimpaqs seem very reasonably priced, I'd just have to wait longer for shipping.
Any opinions on putting a 24" fixture on a 20" tank? The ends are dimmer than the middle, so there's not a ton of light waste.
Goal: High light 10 gallon. So many people offered me clippings for my 2.5 gallon desktop, that I am not sure I have room for all the promised plants. I want the 10 gallon to serve as my "art box" for the other two more aquascaped tanks. Given that the WPG
rule breaks down on very small and very large tanks, I think I've correctly estimated that 2 T5HO or 3 T8 bulbs would equate to high light. (Unfortunately the slimpaq 18" seems to not come in HO
, will take quite a few of those.)
