Thanks for your reply. Very helpful.

By the way, how do you get on with your pressurised Hoselock filter?
Is that the one with the small hexagonal-shaped foam inside?
We used to have one of those in our old smaller pond and found it a
right pain! The foam inside ours needed rinsing every few days and
the water flow kept reducing down to a trickle very quickly. Do you
also have that problem?

It's a Bioforce 2200. The sponges are circular. Output goes to Hozelock
Ecocell 2200 box filter. This was added 10 days ago, and has had a dramatic
effect. Although water chemistry is fine and stable, over the summer the
clarity had declined. I can see the bottom again! Pressurised filter
needs cleaning every 3 weeks or so. I don't wait for the red indicator to
rise fully. I do the pump (Titan) at the same time.
