I don't think the TA is an issue immediately, but reaching a point along with CA that clouding could happen with a higher pH.
Nothing to worry about now, but if TA and CH increase over time, could become a problem.
The FC will stabilize if you completely killed the algae- did you maintain shock levels until no loss of FC overnight?

The clear rough may still shield out UV, so may change overall picture (indoor pools and outdoor pools are different!)
