Thanks to Cliff and Vahe for at least trying to answer what might have seemed a
silly question. I did mention that I had tried the swirling about in a bucket
technique, and that it had taken a long time and a HUGE amount of drought
stricken London's precious water to get to a clear run-off point, with only a
half bucket or so full of sand. I now have a much larger tank to provide for,
and I don't want the water police round........

However, I think the response from DQ was quite un-called for in it's
patronising and facetious tone, I know irony does not travel well across the
atlantic in either direction, but even after making allowances.........

Most substrates are NOT anaerobic, otherwise nitrobacter and nitrosoma could not
live there, and H2S and other nasties would prevail

No Dan, as in "in suspension"

Thanks again

No-one mentioned drying.....

Which comes, as I do, from England BTW
