Hey everyone,
I’m running a hang-on-back refugium on my 55-gallon, and the issue is that the glass panel of the refugium sits right against the wall. That makes it hard to mount a refugium light or do maintenance back there. The unit has a small built-in skimmer, so I’m wondering:
Any tips or pictures of setups would be greatly appreciated.

- What workarounds have you used when your HOB refugium sits flush with the wall?
- Would side-mount lighting or clip-on options be effective, or do I need to pull the tank out?
- Is anyone running a refugium light on the front or angled somehow instead of directly behind?
Any tips or pictures of setups would be greatly appreciated.
