American Marine Inc. was started in 1989 by a devoted aquaculturist who was passionate about quality and precision. Back in the late 80s, critical water quality parameters were mostly tested with colorimetric test kits. Some digital instruments were borrowed from university or laboratory sources with mixed results but always a high price tag. Expensive European aquarium equipment was always a disappointment when it finally arrived. Inexpensive "pens" gave no better results than color test kits and prematurely failed even when testing for approximate readings.
