Went on vacation came back to algae

[Skiddy]

This was our first getaway since we had the pool built. I checked all the water levels before we left and all was perfect. We were gone for 9 days and from what I was told it rained every day we were gone. The pool was full over the skimmer for at least 7 days. It wasnt a green swamp but when I went to brush the sides and bottom it got a little greener and cloudy. I watched the slam video and proceeded to adjust my ph to 7.2 I added enough chlorine to reach nearly 30ppm. Ran the pump for 24 hrs and things are looking better already. Do you recommend cleaning the filter when things clear up and also at what point do we think its fully under control?
Thanks

Nah. It’s a baby SLAM and not a swamp. Once complete, clean it then just because. Or *do* clean it if the psi rises 25%. But it probably won’t.

at what point do we think its fully under control?
Thanks

Pass the Overnight Chlorine Loss Test
Clear water
CC of .5 or less

Keep us posted.

What do you think was the primary reason for the algae growth given the info I gave?

Unless you ran 24/7 in the absence you had cold, 0 FC water stratified on top of the treated pool water. A lot. Until the pump kicked on for its next cycle. It may have only taken once when the bad water mixed in 12 hours (?) later. Maybe the pool fought a noble fight for the first 7 days ? Maybe it was a little bit worse with each storm ? We may never know.

But you know what TO do, so you are golden !!

Thank You. This is my first pool so I like to sponge up on the knowledge where possible.
This site has been an asset.
