I use the red sea tests. they are decent, but expect that alk test to be general readings. low, med, high. I would pass on that kit and go salifert or aquarium pharmaceuticals, they are a good bang for the buck and somewhat precise on readings.
I use AF for phosphates and the rest I use red sea master test kit. The alk one sucks! :mad:
