How much HOB is too much?

hey reefers
I've got a 50 gal Hagen tank. Currently running an hob reef octo skimmer, hob seachem media filter and hob uv sterilizer. I understand it's a lot of clutter but I really don't mind. Anyway I want to add an hob refugium but my concern is tank/glass failure do to weight on the back glass. Thoughts? Personal success or tragedies?

I ran into the same issue prior to upgrading to a larger reef system with sump. I built a small frame behind my tank to rest my HOB equipment off of. Everything wasn't equal height so built it for the heaviest equipment (HOB Fuge) and mounted reactors to it where I could. That being said, yes, I would worry about the pressure on the tank. At the very least I would imagine the seals would decline in longevity.

That's not a bad idea you got there. I too plan on upgrading in the futur but I move around too much right now too upgrade.
Got any pics of your support system by chance? I've got a couple ideas in that regard but curious what worked for you.

Understood, unfortunately I do not. Honestly, all it amounted to was a frame (square) built of 2x4's cut to the height to support equipment. If you go this route, you can cut out the top (where your equipment would rest) for varying heights. This way, if your fuge is short, but skimmer is long, both can rest against the frame vs the back of the glass. The only real issue is if you have enough room behind your tank; you may need to drain and move the tank, or just use smaller lumber to build your frame. 2x4's aren't entirely necessary, but I had enough room for them and it was a piece of mind knowing it was strong enough to support my equipment.
