Ok so I just retested and now I’m even more confused because the levels look better.It does appear to have some recession, once you get your levels all worked out, it should be fine. also what lighting do you have? and also what spectrum are you on?
pH = 8
Ammonia and NO2 = 0
NH3 = anywhere from 0-5 ppm but hard to tell with the shade
Salinity = 1.024
Mag = 1470
Calcium = 490 ppm
Alkalinity = somewhere between 7.7-9.3 dKh
Highest PAR lighting is 120
Flow medium
Spectrum is mostly blues and violet, very little white through most of the day if that’s what you meant.
Thoughts?
