Hey Tom !!! Did something happen ? Like a big storm dumped a lot of silt-y runoff ? If not, your cartridges will filter any pool in the land just fine.
ironically, a slightly dirty filter cleans even better as all those particles trap smaller particles and increase its performance. At some point the flow becomes restricted so you clean it and start over, but without an event you’ll never get to where you need to do more.
Do remember that as the filter gets 'dirty', it will filter to far less than 10 micron.
But, IF, you have a large infusion of particulates all at once, that are finer than the filter can filter, then a high quality clarifier can be used ONCE. A specific use such as that is fine. Chitosan based clarifier (such as SeaKlear) have been shown to be the best.
