Vaccuming the pool using backwash, or on filter mode?

[juamon]

I just cleaned my Pentair FNS Plus DE grid filter. I have lots of dead algea on the bottom of my pool. Can I vaccum my pool using the backwash mode? I don't want the dead algea to stay on my filter and dirty it right away, or must I vaccum using the filter mode because I also do not want the algea back in my vinyl pool? I also do not want to cause any damage to my pump or filter system. Thanks.

juamon,

If you have a "waste" position on the valve on your filter, you can divert the water out of your pool. This uses water very quickly, but you may have some success with that.

The "backwash" position only reverses the water flow through your filter so that would be unacceptable.

If you can't deal with all the water you will lose on waste, simply vacuum in the filter position and plan on cleaning the filter often. It's job is to catch the junk coming from the pool so I would let it go to work.

agreed. The cost of replacing the D.E. after cleaning your filter at about $2 will be far less than replacing the water after the "waste" process which can be 10-20 times that in water/sewage!
