This rock is by far the most afflicted:
As you can see, the one right to the left of it hasn't got any on it at all. I'm not really sure what can be done, given my params. Everything is normal, phosphate, nitrate, dkh, calcium, magnesium. Could my salinity have anything to do with it? Last I checked, it was 1.025.
That was with a hydrometer, though. I actually got a refractometer, but I need to get calibration liquid, since it wouldn't calibrate right without.
Silicates also occured to me, but I have been using RODI water which tests at 0 ppm on the TDS meter.
