Hello. I am looking for a digital probe that will test for pH, dKh, calcium, magnesium, phosphates, and nitrates. Can't seem to find anything like that. Not interested in testing temp or TDS or that stuff. I have that covered. I dont have a dose system yet so no limitations on capability. I'm looking to move to that stage next with my 210 gal. Need reviews from trusted reefers of a test probe that can be trusted. Thx.
