I am wondering if anyone has built anything to hold the lights over the tank. I was gonna buy one at the pet store but it was going to be 30 bucks! So I thought maybe I could build one cheaper. Any ideas would be great! I have a double dome light and a uvb light I would want to attach to the fixture.
I use the commercial adjustable lamp stands for my dome fixtures and they're great for adjusting the height and getting the temps dialed in (and keeping the domes up off of the top of the tank).
If your tank is up against a wall, you could mount bookshelf brackets into the wall above the tank (very securely) and hang the fixture from that. Most good fixtures have clips that allow them to hang easily from chain or wire.
You could probably put together an adjustable stand for a dome fixture in a similar way but I don't have a tutorial for that.
