    Backflush valve leaking water and air...

    My backflush valve leaks now and was thinking of trying to fix it our cut it out and not have one, as I do not back flush anymore. This is with a de filter. Also I really hate cleaning the de filter (8 blades) as it is a bioch to clean and put back together without the seal at the split leaking water. The filter is probably 20 years old as we have had it for 13 years. I was recommended a cartridge filter but not sure about the algae problem. I do get green algae in the summer that I have to brush off the sides of the pool that get max sunlight on them. Does a cartridge filter add more algae issues?

    The type of filter does not cause algae problems. You need to keep the chlorine levels correct and you won't have alge problems.

    If you are not happy with the maintenance of a DE filter, consider sand. It is the easiest to maintain but NO TYPE OF FILTER will get rid of algae.....Proper chlorine does that as WASP says above.
