Ready to SLAM

[Joel B]

I was under the impression that once water temps dropped below 65 algae would not be an issue. I have ignored my daily routine and have checked the water once a week. Yesterday I noticed a ton of backswimmers in the pool. I assume this means I have algae. There is no algae visible, my water is clear. I am able to call heads or tails on a quarter in the deep-end. If I brush the steps, it looks like there is dust in the water. Is it possible that this is a form of algae? It looks light brown. So, should I slam until the dust and the bugs are gone? FC is at zero, water is clear so in theory all I would need to do is pass the OCLT?
TA-110
PH-7.2
Cya-50
FC-7
CH-380

Another question, should I lower my CH level prior to the SLAM or afterwards?

Each year our pool gets back-swimmers and/or boatman bugs. Kind of a seasonal thing regardless of the water condition. But your FC should never be at zero, so make sure to balance that according to the FC/CYA Levels.

My entire neighborhood is infested, all of the pools filled up in the last few days. It is the strangest thing

I meant my CC was at zero, my FC was at 7
