SkyCatcher,
I think that 8.5 is perfect for pH. Who in the world told you to lower it
to 7?

Hi,

The pH is 8.5 - reading taken at 2pm & 6pm. It used to be OK & the tap
water
is 7.

How much white vinigar would be needed for 10,000litre pond to get to 7?

Hi,

I've read that you can filter through peat to reduce pH. How do you
actually
do this & what type of peat do you use?

I can only think of the big bags you get at B&Q for your garden & as
this
is
very fine how would you stop it just being washed into the pond?

Any help gladly received!
