Thanks Zoom, the Urchin is a great skimmer. The hob skimmer is the remora and remora pro. I have a hang on back skimmer, but its not the Aqua "C". The Red Sea Turbo is a hob skimmer for tanks up to 250 gallons.
I also have 2 Seio 820's for sale. I will take $50 for both shipped with insurance.
Thanks
Mark
