A_Lee said:I used a CPR HOB Refugium on my last 40g reef tank. IIRC, I used the smallest sized one out of the three. Minimal assembly required, and it came with everything you needed. It worked well for me -I have no complaints about it, as it did it's job. Chaeto grew like no one's business, and it is easy to take off and clean if need be. Built fairly sturdy IMO.
