And I thought I heard them all!
Yeah, those things are frustrating to read. If they were honest they'd say Yellow=0ppm, Orange=5-30ppm, Red=Water change.so i did my yearly nitrate test today on the 500 and 600 and i have no clue what the nitrate level is on the 600:

Maybe someone can tell me - i think aruond the 5 range which is a bit high i guess. The 500 was more yellow.
Hum. I guess it is getting rather high; maybe next week i'll do a 200 gallon water change on the 600 - kind of a pain.It appears to be between 5 and 10. Remove the cap and look into the vial through the top instead of from the side. That usually offers a more accurate color indicator.
