Minor Alge "cloud" when brushing

[Thorn]

I brush the pool side and bottom at least once a week, usually more. If I wait 4 days or so what I get when I brush is a slight alge cloud . I bough a vacume head with brushes so that when I brush it would go straing to filter, but the vacume head I bought is next to imposible to push on the pebbletec surface.

My CYA is close to 50 and FC is usually at least at 4.

So.....is that alge "normal"?

Can anyone reccomend a vac head that will work to get this minor alge off the floor and into the filter that works well on pebbletech surface?

Or, do I just brush it, forget it, and let the skimmer / vac deal with it?

I can't help you on the brush but you might consider upping your FC level. A CYA of 50 has a min FC value of 4 and a recommended range of 6 - 8. Have you done an over night chlorine loss test recently? Algae is not normal for a clean pool.

Hello neighbor.
Have you tried an overnight free chlorine loss test... Overnight Chlorine Loss Test to diagnose that you have an algae issue? (typing while DorsalSpine posted)
What you may be seeing is ash from wildfires in our area settling on the bottom and in the skimmer.
The last week I have been seeing a grey accumulation on my pool bottom and in my skimmer net and I know it is ash as I can see it rain down from the sky. It also accumulates on the cars, umbrellas and everything else.
I use a robot pool cleaner and can also see the grey ash in the fine filters.
Do an OCLT to properly diagnose your issue.

Will do the test tonight / tomoroow morning.............kind of wish it was ash the i'd know it would just stop eventually. But it's for sure green.

That doesn't sound like algae, not much loss at all.

I would probably still bring FC to SLAM level for a day or two and then maintain FC between 6 and 8ppm. 4ppm for CYA of 50 is the bare minimum and your pool should not see this level too often.

I'll see if the cooler weather has any effect for a few days, then raise the level if it does not..

As mentioned above, maintain your chlorine level in the 6-8 range because your CYA is at 50. “usually“ at least 4 is operating at the bare minimum and asking for trouble. Good luck!
