How much heat does this thing give off?
The reason I'm asking is I plan on running and Eshopps HOB skimmer and I think I have enough room to slide this between the skimmer and glass but it's going to be real close.
Love to have an answer on this, as I think I'm going with the same setup. I've run several skimmers over the years (stock, sapphire, tunze 9002), but want to add a fuge+chaeto to help curb the pH swings (amongst other things). I tried the AC70 HOB mod for a fuge, and while it works great the the return is an overflow and is louder than I liked (well, louder than my wife likes anyway

).
The problem with the AC70 HOB mod (besides the noise) is that it is pretty large and covers the entire center chamber (where you run the media basket with filter floss, chemipure, and purigen) and doesn't leave room for an HOB skimmer besides the AquaC Remora (with a slight modification).
The goal would be to run the Stevie T basket (with the afore mentioned media and JBJ nano glow) + the Eshopps 75 HOB. Keeping everything in house except the skimmer.
Jason, if you have already setup the Eshopps 75, can you tell me about the noise and how the pump fits into chamber #2 (the stock skimmer chamber), any mods needed? Also, it is one of the only skimmers on the market that actually pipes the return into chamber #4 (as opposed to the overflow return, which as I mentioned before is too loud for my application). If anyone else wants to chime in, do you know any other skimmers that run the pump INSIDE the tank and run a piped return directly back into the tank?
