filter short cycle

[rhd01]

Just opened pool this weekend and my filter won't run more than 1 hour without having to back wash never had this problem before.

Is your water full of algae or debris?

[rhd01]

Yes lots of algae also noticed sand after backwashing on ground

[Watermom]

That would explain the frequent need to backwash. The filter is catching stuff. So, it is doing its job. Might be a good idea to post a current set of water testing results taken with a drops based kit for us to take a look at.

Thanks is it normal to lose the sand out of filter when back washing

It is normal to lose a small amount of sand when backwashing.
