Ok, so I know this is a highly debated topic, and ultimately most people recommend both ultra low range checkers, but my question is for a newly set up tank where phosphate could easily be above the maximum range of the ultra low range checkers (0.9ppm i believe). Would it be better to get the low range checker while a tank is Cycling and stabilizing (first 6mos-1yr), and then buy the more accurate ultra low version later on down the road.
