Good news, I got my nitrates down to 15ppm. Gonna do a few more water changes this week.
Water Changes work like a charm. Now that you've got your nitrates to a more acceptable level, it's time to work on the other stuff to help keep them at an acceptable level. We've spoke about the stock list issues.
As for the RO/DI, I recently purchased a Coralife Pure-Flow II (1 micron filter cartridge, 1 carbon block cartridge, mixed bed deionization cartridge) 50gpd for $175. I LOVE IT!
If you're really on a budget, API makes a tap water filter. They work quite well, I even filled a 155G with it. The issue is the cartridges don't last that long, but if you only have a 55G, you should get some decent use out of one. The unit costs about $50 and each replacement cartridge is normally $25-35 and each should last about 3 months for what you'd need.
