Intex Sand Filter, still having an issue with pollen

Hi All, we opened the sand filter last night after having flow issues...it basically works for 15 minutes then quits. We have very high pollen, it was caked on top of the sand...we scraped off that layer, added more sand and it worked better last night. I added a pool sock over the poolside skimmer, but we’re still losing flow. I can’t seem to find anything about this on google, and I am just feeling super frustrated. Do you think we got a bad pump? It’s less than a month old direct from the manufacturer.

Can you let us know what equipment you have? Your signature being filled out is a great help.

Basic, small, under-powered Intex pump/filter systems are not designed to handle significant solids. You may just be overwhelming it.

I doubt a pool tech will do much more than backwash it. But up to you.

We’ve just really been worrying about the free chlorine, ph and alkalinity...those are all in normal ranges. Is there a chemical rating that would help us with this?
A basic test kit and process is fine if this pool volume is 3000 gallons or under. You would then just drain it whenever your water turns cloudy or algae appears. But if your pool is of larger volume, you need to properly manage the chemistry.

Thank you...we have the taylor 2006 kit and we have been using chlorine tabs in a floater...the chlorine levels have been around 3ppm consistently, and the PH around 7.2, and the alkalinity around 80...the stabilizer has been in the low range...but I thought that would mean we just might need more chlorine?

Ok. You have it filled to proper level, and were cautious about pouring around the upright, correct? Do you find any sand coming into pool from the return?
Yup, we were careful filling it around the cap...a little sand came in because my husband forgot to rinse it before the restart after the top
Off last night. But the filter problem was happening before that.

I kinda want to see what is happening right after you backwash and then rinse. Does your pressure gradually increase, shoot up suddenly, is there air in the pump, etc.? All valves are open?
