Great news- I got a refractometer today! No new pics to post, as it looks exactly the same as yesterday.
I tested the water again, after adding another pinch of flake food.
Ammonia= .25 ppm
pH= 8.1-8.2 (again, so hard to tell with the color card)
Nitrite= 0 ppm
Nitrate= 20 ppm
temp= 77
SG= 1.024
I topped up the tank today with distilled water. After the cycle finishes, I'll start doing pwc's with distilled water. I'm sure the tap water is causing the nitrate reading, thus the switch.
On another note- Oceanic brand salt is awesome. I only had experience (from work) with IO and Tropic Marin (which is clearly better than IO). I was really impressed with the Oceanic because it dissolves so quickly, and you don't end up with that grainy stuff at the bottom of the bucket like with IO.
