Thank you.
If there's more to say, of course I want to know.

BTW, I've ordered the recommended filter, the Hayward C3070, and a Pentair Superflo VS. They'll be installed next Friday, September 6th.

Re: How do folks backwash?
I'll try to get back to this before Tuesday, but I'm glad. I hope it works out really well for you.
One of the additional reasons for an oversize filter that I hadn't mentioned is the problem of VS pumps. Most of these pumps -- including the Whisperflo VS -- are actually extremely high volume 3HP pumps that can pretty much DESTROY most smaller filters if they are inadvertently run at full speed / full power! They ought to come with a key-locked maximum setting, based on the filter & piping they were matched to, so this couldn't accidentally happen.
The Pentair Superflo VS is apparently 'just' a 1.5 HP pump (PLENTY large enough for a 20K gal pool!), so the problem is reduced. Even so, that pump can potentially generate nearly 40 psi, if driven against a dirty filter that is undersized!
Re: How do folks backwash?
The pump and filter were installed yesterday, and so far they're working very well.

Thanks for the follow-up. If you can, please set your phone to remind you, and let me know how it's going in a month.
One of the problems with the forum, over the years, is that a lot of advice has been given that disappears into a black hole of 'no longer term feedback'.
