Does Cloudy Mean SLAM?

[kawisser]

Is it that simple? If the pool is cloudy then follow the SLAM process?

When i first opened the pool, it was crystal clear. We had a week of rain, and I neglected it for 8 days. Upon opening, it was cloudy. I gave it a good brushing and vacuuming today and am doing the OCLT tonight.

Depends on why it’s cloudy. The OCLT will tell you what it is.

No CC in your PoolMath logs, but yes, the long period with FC very low (1!) That fast drop of FC after you added yesterday seems to want to tell the tale, in addition to the cloudiness. An OCLT will double confirm what you pretty much know.

Cloudiness can be for a number of reasons, so is not the automatic sign to SLAM. The OCLT would be. But you've got multiple things throwing flags on the field.

Glad you mentioned CC. Tbh I never test CC. I didn't even know that was available to track in the app. I see now that I had CC disabled in the settings. I'll measure that in the morning as well.

CC is a measure of chlorine that has been converted by organics into chloramines (and other stuff) - it's that "chlorine" smell for a pool that people notice and hate. Essentially how "dirty" the pool is. 0 to .5 is fine. 1 or above, and something is consuming the CL. Could be those worms from the rain, could be from those 238 people you had in the pool this afternoon. Or many other organics. They escape from an open pool into the air fairly quickly. If nothing continues to use CL, it will then reduce on it's own (you got those worms out, everyone went home, etc.). Adding extra CL will help move it along. Algae by itself does not make CC. But a higher CC may mean conditions are better for algae to have nutrients to use. So another flag to help with "To SLAM or not to SLAM?"
