I have a 20 long nano reef that's been set up about 3 months. I do weekly 20% water changes but I've started getting some greasy residue on the surface of the water. What do you all recommend for a good quality but not overly pricey protein skimmer? I don't have a sump or refugium, so a HOB skimmer would be ideal.
