I wouldnt worry about spending the money on the test kit. Im pretty sure its diatoms, if it were cyano
you would know it by now and your would see a slimy stringiness to it. Unbound silicate is all that kit will test for. It will not test the silicate in the sand where the diatoms are feeding off it.
If your concerned about your RO
filters then o suggest you use the money on a TDS
meter instead of the test kit. If you have anything but ZERO TDS
then you need a filter(s) change.
If you have Zero TDS
the your water is silicate free along with everything else.
