Not in York Simon (drawn from the river Ouse here). It is more or less dead on 7 normally (neutral PH), slightly hard. I don't have the exact figures to hand.

Although a lot of the water comes down from the moors and dales (acidic), it also flows over and through Limestone.

Fine for livebearers and African Cichlids, plus most 'tolerant' species.

Discus you'd need to take it down to about 6-6.5 softness, and slightly acid (plus of course, the frequent water changes). This would go for many of the South American 'Amazon' species if you wanted breeding success.

Used to keep and breed Discus a few years ago, used to have a RO unit and then filter through peat to get the ph down.
