What level of silicates would be considered high? reactive Silica
levels in the local water supply were between 7-10 mg/L for the last
few years according to the city water report. Total Hardness is less
than 30 mg/L. It's very soft water so I keep a small bag of crushed
coral in the filter to buffer the water a little bit. The last I
checked I could not detect any phosphates using a Hach colorimetric
test kit.
I have not looked at anything with a microscope to determine if it is
diatoms or bacteria. It doesn't grow fast and is only on the oldest
leaves of my plants.
Thanks,
Bryan Nielsen
