LF: HOB protein skimmer Edmonton
 

Hi there everyone,
Looking for a protein skimmer that is HOB (external I think?). I have a 90 gallon and already have a protein skimmer rated for my tank, but I want an extra one as I think I have too many nutrients in the water column. Yup, already starting to feed less, but still would like super clean low nutrient water. Please let me know what you have and what you are asking for it. THanks so much!
