Help with cloudy pool

[Brodx]

I have a 15k gallon guinite salt pool that is cloudy. CYA is only at 35 or 40 (hate testing this). I’m trying to raise that but my FC is at 5 so I would think the low cya isn’t causing the cloudiness. Below are my full readings.

FC 5.0
PH 7.4 (cpl days ago was at 8 )
TA 80 (Cpl days ago was at 100)
CH 290
CYA 35

My understanding is cya helps protect the free chlorine from the sun and elements. So if cya is low, means low or no FC which is what causes problems but I don’t have low FC. CH is on the low end but I wouldn’t think it would cause cloudiness.

Any advice? Thx!

Welcome to TFP.

CYA is only at 35 or 40 (hate testing this).

We round up. If the dot disappears between 40 and 30 you call it 40 and move on.

Do a Overnight Chlorine Loss Test. If you fail the test you have algae and need to follow the SLAM Process

Will do it tonight, thanks!

Happy Easter! I passed the overnight chlorine loss test. Any other recommendations?

Nvmd pool looks quite a bit clearer today so I believe we are headed in right direction. Not sure what I did though, lol
