So I thought i was dealing with GSA here, but others think it may be GDA or BDA.
It doesn't rub off leaves, a tooth brush will take it off though (and nerites, have a dozen coming this weekend as they dont' last long with my soft water).
EI dosing + Iron, lots of CO2. GH is about 5, KH 0-1.
po4 is 2.0 PPM
Nitrate is about 40-60 ppm
