How is the light resting on the wood? I see like a full wood cover in that bottom up shot. I would paint the wood with some type of water-proofing material so it doesn't warp overtime due to evaporation as PinoyBoy mentioned.
the light sits on a full wood cover, that's resting on the top series of bolts. I haven't cut the hole for the light yet, as I don't have any tools to make that an easy job. I plan on cutting a hole, and then making some sort of posts/guides so the light can't move around too much.... Make sense?
I'm not planning on filling the tank for a while yet...I'm still reading and getting to know what all I want to put in it.
Thanks for the feedback. Cheers.
