Algae problems sources have been known to be lights changing spectrum as they get old.. Doesn't mean that is the root problem..heck it could be just one of many.
You havn't told us yet your test results. Every algae problem I had was due to Phosphates being up.
But I agree with the big clean up idea... Personally if it was that bad for me, Which I came close but not that bad...
The clean up may be a big task. Have you considered doing something more drastic to really punch that algae in the mouth? For example:
Like tank transfer prep work… putting things in separate tubs (rocks and livestock separated). Keep a heater and flow in the livestock tub..
Clean you rocks in a bucket of tank water… and do one mega water change..im talking about 75%.. Then put everything back in.
