That doesn't seen excessive. You have additional surface area and water flowing over overflows.

I live in Arizona, and my 180 loses on some days almost 2 gallons!

Think about it, the average humidity here is about 15% all the time!
I get out of the shower and before I can finish toweling off my hair dry.

YUP! Remember to add buffer to your top off water or you will lower your tank PH

The PH buffering doesn't stay.
What I mean is that when I make a large can of R/O top off water, I added the ph buffering to set to 8.2. But after I had the water sit for a day or two, the ph lost its hold and it dropped. That is with nothing in the water, no food, fish - zip. Just the R/O water and buffer.
I think the ph buffer is just temporary - it doesn't keep. I have learned that you need to do frequent water changes, keep excess food out and soon I will drip kalkwasser.
Thats my 2 cents. I constantly battle a falling ph value.

I lose about 1 gallon a day in a 55 (70 gals total water) here in CO.......

Running a 120gal with a 29gal sump/fuge. With 500watts halide and 192watt pc, i lose about 1.5 gallons with halides on 9 hours/day

Is a sump the same as a wet/dry filter?

 

[hurt]

I lose between 1.5-2 gallons a day on my 55 DT with 20g fuge-~70g total. I have 500w MH and another 220w VHO, with computer fans in canopy and clip on fan in fuge.

A sump can be a wet-dry, depending on how you set it up. A sump is technically just another tank plumbed into your DT. You can put a wet-dry in it, heaters, skimmers, CA reactors, Kalk reactors, phosban reactors, etc. Just depends upon what you are trying to accomplish.

The manual top off is a pain in the tail. I have 3 saltwater tanks, all need top offs. Oh well.
I go through 2-3 gallons every day or other day at the most on my 75 gallon reef with a 10 gallon sump, a gallon every other day on my 90 gallon fish only, and a gallon or so every other day on my 120 saltwater tank.
Yes, tops offs is a job and I find that I make up 20 gallons of top off that I store in 5 gallon ice tea coolers and that when that is used up, I wind up buying bottled water to get me through top offs until I make up R/O water again in the middle of my kitchen.
i cain't wait until one day where I get a plumber in to install faucets handles in the basement water line so I can make continueous top of from down stairs.
No lie, fish tanks are work. But i love my fish.
