I'm not sure. I thought my magnesium was low so I bought a test and the results were 1350. Calc 440 and Alk 11.

It could also be very fine sand particles being blown about in strong flow and sticking to the slimy coating on the glass. Fish-wigglings & rushing around suspend the finest grains in the water column only to be carried around.
