Water came out of ground around 7 ppm. After 2nd section it was 5 ppm. LHO boxes bumped it up to 8 ppm. Went through two more sections and left 4th section at 5 ppm to LHO’s. Bumped back up to 7 ppm and left bottom of raceways at 5 ppm. Great efficiencies transferring oxygen into 5 ppm water—up to 90%
