Pollen is sticking to the outside of my hot tub filter input (where the water gets sucked into the system to be cleaned/circulated). I scrape it off and it immediately reattaches. Is there a way to get rid of it without draining the hot tub or buying a pool vacuum?
Keep the hot tub covered when not in use to limit the amount of pollen if possible. Also check that the water level is sufficient to get good suction going through the skimmer as you may have a certain spot that is collecting the pollen where there is no circulation. The filter should be able to take care of most if not all of the pollen, but may require more frequent backwash. Another idea is to add a clarifier that will clump the pollen so that it can be removed manually or by vaccuum. Last, there are devices you can place in your skimmer that also help to collect the pollen so that less of it ends up on the surface of the hot tub.
