That dose seem like alot, my 225 TWV of 350 only evaps about 2-3GPD. I think that trickle design along with bio balls allows alot of air exchange and is probably why you evap so much. But really its not a big deal is it? i argee with H2o sayin filter socks are great, i love mine my water is clear as can be. Tops help alot but i hate the one on my DT because it gets salt creep underneath and reduces the light quiet a bit IMO. My tank is in the basement and i like the tops for the fact they keep the heat, however that can be an issue for many systems with hoods and enclosures that already battle with the temp getting to high in winter.

Re: water evaporation
I am using a wet dry sized for up to 400 gal supposedly. Had three chambers. Two bioball towers and an empty area for pumps etc. Originally I had one tower full of bioball fed by one return over the drip plate. Another area full of chaeto and macros and live rock. When I removed the bioball i also removed the drip plate. I kept the eggcrate in the sump that the bioball sat on and put chaeto in place of bioballs. One 90 drains to each of the two different chambers now. Sump is happier with more flow. I havent noticed any negatives from removing the bioballs.

I'm thinking that surface area plays a role in evaporation. As in more water surface exposed to air = higher rate of evap. Is that right? And air flow, too, probably. A tank in the flow pattern of a vent would almost have to evaporate more than one in a dead spot, or covered with glass that prevents most air from brushing across the surface.

Correct also the pipe running from display to the sump bubbles and creates more evaporation also the size of bubbles coming from your skimmer I have put a top over where all the bubbles come to the surface in my system to reduce evaporation which helped tremendously also if you run hailides you will have more even t5s u will have more than leds

In addition to the surface area that Cindy mentioned...surface agitation plays a huge roll in evaporation. As others pointed out, if you can cut down splashing in the sump that should help a lot. Also take a look at your display and where your powerheads are pointed. Without a lid, if you are getting a lot of rippling on the surface, that would contribute to excessive evaporation. I know when the water level on my FW tank starts to get low, the evaporation accelerates since the powerhead is only a few inches below the surface. Just keep in mind, if you do adjust any powerheads in the tank, that some agitation at the surface is necessary for gas exchange, but you can minimize it quite a bit since you're using an overflow and sump.
The trickle stage is what's killing ya, heh. I remember with my old wet-dry I lost a couple gallons a day from a 60g. My current 60g also has a cool trickle spillway in the back AiO "sump/chambers" area. Great for Oxygen exchange, but noisy as hell and evaps at least a gallon a day.
It's the Colorado dry air, combined with this, similar principle as how a swamp cooler works:
