Algae starting when FC is perfect?

[steveg_nh]

Hey guys,

I usually don't have any problems, but might this time, so thought I'd ask. About 2 weeks ago, my pool was a bit cloudy. I SLAMed it and passed the clarity, CC, and OCLT tests with flying colors. Pool was great. SWG is running, and the FC level as tested this morning is 6, and CC is 0. Everything else is right on spec, and CYA is 60.

Anyway, pool is cloudy again. We did have some storms, so maybe an excess of junk got in pool? But curious how algae can start up if FC has been good and not dropped. I'm going to have to SLAM again to clear the cloudiness, just hate using all that liquid chlorine if I could have avoided it somehow. Just not sure what I could have done. Pool has tested great each day.

Thanks!

Are you brushing the pool regularly.? Could there be anytime that the FC has dropped below the minimum?

I would consider bringing the pool up to SLAM level and then performing an OCLT.

Check all your nooks, crannys, lights, ladders and such.

Areas with poor circulation can get algae. That's half the reason to brush -- to get the chlorine-laden water everywhere.

Thanks guys. Water is already crystal clear again. I'll hold it at slam level for the day and try the OCLT tonight.
