pressure guage

Postby Guest » Fri 27 May, 2005 18:51

What should the pressure guage read on a sand filter? It is hovering around 18-20, sand filter. The pool is over-ridden with algae and I backwashed twice, but it is so green I can't tell how long to backwash.

I also can't get rid of the algae. I have shocked it twice, today with 4 bags and used the spot kill. It is still a very dark green almost black. How long should it be like this and should I use anything else?

We are new at this and the pool was here when we bought the house.

18-20 sounds good on the gauge, you probably want it no more than 25

Sounds like you need a LOT of algacide. Have you gone to a pool store to ask their advice? You should.

You should also read the manual for the filter. If you don't have it, try the manufacturer's website.

My pressure gage reads around 10-12...you are supposed to backwash when it get 5-7 over initial start-up pressure.
