I have the 3000 model and love it. The pump has been reliable, quiet, and pulls in a lot of air. The gate valve allows for easy fine-tuning. The skimmers is very sturdy and does not feel cheap in any way. I believe the 2000 model should be more than big enough for 2 80 gallon frag tanks.

yes, it's rated at 180gallons

At that price point I would go with something like this.

I own one of the bigger ones and wouldn't trade for the world. No tuning necessary.

I own this exact model and love it. As stated above, the gate valve is a must and great for tuning. I picked this one because of its more cone like design, which I feel most manufactures are going towards these days. I don't know about the Reef Dynamics one, I feel skimmers need to be tweaked to perform best. A perfect example of this is how much the water level in the sump, and the result it has on the production of the skimmer.
