Whether that is the case or not, it does help. 10 times the amount is typical but for 10 times larger systems often so its the same ratio if a 300/500 is used on a mini reef 10-30G. Anyway, the HOB fuge is nice for growing pods as well and also for surface aeration if you don't have an overflow. More reasons to have one than to not just because of its limited size.

That's my $0.02. And yes, I have an AC300 on my 33g and I have mostly halimedia sp. in it as well as in the main display. Helps the pod population otherwise for my blennies.
