Well, as I've finally settled some things down in my apartment, my tests can officially begin. I got some ghost shrimp, which I had to keep in the 3 gallon for a while, and it started getting that same thick, icky feeling in the water that usually comes before the film. But, now all the shrimp are out of that tank, and in with Sonas, so the 3 gallon is empty.
My first test is of regular tap water in the 3 gallon with ONLY the heater. No stress coat, no decorations, no gravel, no stock. Just started it this morning, so now its a waiting game.
