Did a test on my low tech tank last night and tested the potassium and magnesium for 1st time as did have little trouble with few crypts with odd leaf getting yellow with tiny black/green pepper specs all over leaf and melt
the readings was
potassium around 18mg/l was off scale on jbl test kit
magnesium 2 mg/l
are these way out and need putting right for health of plants and fish
