Have everything I need but the Archea LED. (Though, I think I'm going to use the current 45-F I've got as a coral frag tank and maybe order a second to use for this project.)
I could build my own fixture using aluminum C-channel but would prefer not to suspend anything above the tank.
Actually a bit undecided on the substrate. It's between the variety of pool filter sand I've got and ADA Aquasoil - which a lot of people are using these days for BTOE without any problem.
Hope to have time to get things going in the new year.
