This way you know how much a tbsp (or what have you) will raise each parameter. Then when figuring out your doser you can test, add supplements to bump it up to where it should be, test again to check. Bump the doser up a smidge depending how much supplement you had to add. Test again tomorrow. After awhile you will be testing, dosing, and adjusting the parameters every 2 days, then 4 days, then once a week. Some months down the road you might be able to test once every 2-4 weeks. Test LOTS, and try to keep things stable.

I have a fuzzy millepora that 90% of the colony is as furry as a chipmunk tail but there are a couple branches that have very slowly turned green like this. I'm dosing NO3:POx4 (Red Sea) and even though the part of the colony that is green still has polyps they don't typically extend very far. Is it the same situation as this fellow? My alk has stayed between 180ppm-220ppm for months and this greening started before I started dosing POx4.
