Thank you all for your input. You've given me much to consider.
I think I'll probably just get the Hanna test kit for alkalinity, a refractometer, and get cheaper salifert kits for nitrates and phosphates. I currently only have four small coral polyps, and one of them is a mushroom, so maybe when I get several more corals, then I'll get a salifert test kit for calcium.
