Anybody use custom aquariums overflows? I'm debating between them, reef synergy, and glass holes. They're cheaper and seem to have good reviews but wanted to ask you all (you're the experts).
I've also purchased a Synergy Reef and it is much thinner and has a better design that also integrates the bean animal overflow in a small space. I haven't installed it yet so I can comment on how loud/quiet it is but it's a very clean design.
