I have a ASM G-3 skimmer for sale. I used it for about 2 years on my 75 Gal. that I tore down, so it is no longer needed. It is in very good shape and 100% factory(no mods). I purchased the gate valve for it, this makes fine tuning much easier. It comes with orginal box and a brand new impeller. I'm asking $175. I'm up in indianapolis every mon., tues., and thur. so I can meet someone if they are interested.
