Hi all,

We did an audit a couple of years ago and found we are throwing away 1/3 of each can at end of treatment. I barely believed it but following calc shows its true.

4 hrs at 0.5l/min = 120l. HDF -15 litres. Test and priming - 15l. Total =~ 150 litres.

1:44 = 1 in 45. 150l/45 = 3.33 litres conc required.

1:34 = 1 in 35.  150/35 = 4.28 litres req'd.

Simples - get central acid delivery.
