Polarising filter

Having read lots about polarising filters, I bought one.  Down by the Torrens river, I found due to the lighting situation where I was, I ended up using Manual mode, which I don't very often.  Aperture f/2.8 - though I could have gone for a smaller aperture as I was some distance away, but still got a good shot.  Shutter speed was 1/1000th of a second to partially freeze the flow, with ISO 6400 - so high because of dense shade and the polariser reduces the exposure by 2 stops also.  With the polariser on, I experimented with turning it until I could the bottom of the river, the glare having disappeared.  I couldn't freeze the flow quite as much as I wanted but pretty ok.
