Trouble free pool says not to use floc or clarifiers.

How then to remove very fine particles in the water that are too small to filter?

Your cartridge filter will filter out down to under 10 micron size particles. Those are below visible range.

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.

Our pool has gone hazy.

I think it’s either due to gunk from our dilapidated rooftop solar system, or due to recent thunderstorms. I will post another thread about it.

This thread is more a theoretical question - how can a filter deal with particles <10 micron.

Don’t they eventually accumulate? Say you dumped a bucket of clay into the pool (particle size <2 micron), how does this get filtered out when the filter only catches down to 10 micron?

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.

Could be algae? Try shocking (SLAMing) the pool, running the filter for 24 hours for a couple of days and see if that helps. You could also have a tear in the filter cartridge(?)
