new user, old pool, trouble with algae

You won't need to backwash if it's on recirculate, assuming everything is plumbed and working like it should. NOrmally we would advise people to run the pump on filter while the mess is being cleaned up, and with a larger filter on a smaller pump, I'm still inclined to advise you that way. However, this year we've had a ton of folks who are having problems clearing up the dead algae once it's killed, and Pooldoc believes that sometimes it's due to forcing the dead stuff through the sand and actually having it break up into smaller pieces than the filter can catch. So....if it were my pool, I'd probably keep it in filter mode. However, if you want to leave it on recirculate until it's all dead and THEN switch back to filter to get it all out, you can do that too. Either way works, but if your filter is efficient at getting the dead stuff, then the recirculate option may just take a little longer.

I am not the equipment guru around here by any means. But just wanted to share what I have on my pool since the pump size for this pool is being debated. I have a 27ft AG pool (approx. 19,300 gallons) and I have a 1/2 hp full-rated inground pump and it works just fine. I'm inclined to think that a 3/4hp on your pool should be plenty. Just my $0.02.
