Thanks for the info!

So, run the filter until the slime is gone, then resume the normal schedule? I have no chemicals between the skimmer and filter and I don't use tabs. How small is a "small dose?" Half the recommended dose for a pool my size? And how regular should I be dosing? I always add dichlor and cal hypo directly to skimmer.

My pool is 15x30 above-ground btw. My pump is a 1 HP Hayward ProFlow XL that sounds like its on its deathbed. Just had a new pump seal and impeller installed. Looking back, I probably should have just replaced it.

Thanks
