I would investigate a brand-name skimmer to use, or at least find out the exact specs of the skimmer this guy is building for you.
Recirculating just means that one of the pumps is taking its feed water from the skimmer body, not from the sump. Skimmers that come with sumps are notoriously weak, but if this is custom it might be fine. Just find out what style of skimmer it is, the pumps being used, etc.

His skimmers are based on a recirculating and inline design. This is the most effective and efficient skimmer design. It will have two valves for adjustment, one will control the water flow through your skimmer and the other will control the skimmer water level height. The pump in the skimmer is a sedra 3500 needle wheel.
I trust in him that this is a good choice, he has done many many before. Does this all sound good to you guys?

With a sedra 3500, that should be fine for up to about 110 gallons, check out a G2 on www.asmskimmer.com
I would get a bigger skimmer than that though, in case you want to upgrade to a larger tank in the future, or hook in more than one tank to a common sump. Ask him to upgrade to a sedra 5000 at least, the G3 is ASM's most popular model good up to 180g. Plus I don't think you can over-skim. What is going to feed the skimmer water, the drain line from the tank, or another pump?

I havn't got the final design from him yet. There is going ot be an overflow box from the tank down into the sump adnthen into the skimmer, so I would imagine right from the tank. I could get some stuff changed too, he is just in the process of engeneering my sump now. I will ask him about the bigger sedra model. Shouldn't be too much of a jump in price you would think.

Yeah I would get as wide and as tall a model as will fit under your stand. I love my needlewheel skimmer with 3 sedra 9000's bubbling away.
He is probably feeding the skimmer with your overflow water, with a valve to controll how much of it goes into the skimmer. That is perfect, sounds like a good designer. Also make sure your sump design takes into account microbubbles. You also want to make sure that if your overflow fails, your tank can take up the volume of water in the return section of your sump so you don't overflow.

No problem, and welcome to the forum. There is a great community of reefers in Calgary that come on here too, for group buys, and getting used stuff.
