I had an ATB small for about a year as well, I had to sell it in a bind. It was the best skimmer I've ever owned, was capable of tripling the amount of skimmate I was getting before with my Euro-Reef.
I would like to run this on the Solana Scott, but I don't wanna look at it hanging on the back with the cup popping up on the backside. Once I recieve it, I'll re-evaluate that.
As far as everyone getting all up in arms over the cost, it's not even like I'm selling it for 500, I said "make a reasonable offer"
Reasonable has gotta be around 300-350 though for me to part with it.
If I can't sell it I WILL use it on my 90G or the Solana project.
