I probably should have mentioned that I'm doing a dry start--once I get things going I'll probably have to do a shortened photoperiod or change my bulb/distance from substrate to avoid creating an algae farm. I also live in a garden level apartment (read: basement) that gets hardly any ambient light because I keep my curtains closed all day.
I'm gonna try to relax. I've got some tap water in a clean glass that I'll test in a day or two, and then I'll panic about parameters after I've flooded and cycled. (I'm doing a fishless cycle.)
This info has been very helpful.
Bluek24a4: Which parameters specifically? I only have my water report and the basic freshwater test kit, but I'm thinking of ordering some of the more exotic kits because I like spreadsheets and tracking things and titrating. And stuff.
