I have a 25,000 gallon in ground pool.
I have a Hayward 1hp super pump (new) pushing the water through a 300lb Hayward sand filter (used for 2 seasons).
I just got a new liner put into the pool, and since I have turned on the water - I notice a small bit of sandy stuff on the bottom of the shallow end about 3 feet from where the return sprays out water.
I am worried that somehow I the sand filter is losing sand and dumping it into the pool.
Is this even possible?
What else could this substance be? - I never had this happen the last 2 years using this filter.
I sweep and vacuum the pool weekly, and every week its back in the same place!
I am a pool noob - so I always appreciate layman's terms.
