Ok ok you talked me into it....

I’m gonna do a Hob refugium. I’m not sure if I’m gonna do an aquaclear or a “Hob refugium” (same thing really).

My only two question is what do I put into it so I don’t have algae making my tank look like melted crayons?

And

If you were me and were setting up a 40g breeder which would you do? A 70g (or 110g) aquaclear or a CPR refugium unit?

Fijicube also has some nice HOB refugiums. I would go with the biggest dimensions possible. The larger the space the better for the refugium to do refugium things.
