I think we discussed it in your prev posts... i don't remeber for sure. Anyway 1 single Power Glo bulb won't be enough for keeping corals. I used hagen bulbs before, so i was experementing with them. The best Hagen bulb is Life Glo. This bulb has full spectrum 6700K (day light) with built-in reflector. Your lights should be upgrated. You will need to add this kind of lamp to keep at least polyps or leather corals. I had 2 life glo, 2 marine glo and 1 power glo over my prev 110 gal and had success with keeping an thriving of leather, polyps and LPS corals (Frogspawn, Open brain).
My suggest for clean up crew will be: blue legged or red scarlet hermit crabs, Astrea or Turbo snails, Cleaner shrims, possibly brittle star(s). All this animals compatible for REEF environment or FOWLR without invert eating fish like Triggers.
Again, one single 18000K Power Glo 40W won't be enough for corals.
