Looks like the MindStream Monitor is now being sold. It costs $995 + a monthly subscription fee of either $39.95/mth or $34.95/mth. Has anyone been a beta tester. This is a step price to pay, but I'm sure many will be willing if the monitor works as promised. It tests ALK, CA2+, MG, Salinity, pH, Temp, O2, CO2, Ammonia and potassium.
