GHA common few weeks after cycle?

[Reefin' Alaska]

Had to swap tanks, won't get into that. But, had to re-cycle with fish in system, not by choice.. Used Microbacter Start. Got thru that.

ICP came back pre-hair algae growth 0.28 P04. Nitrate is reading 2-5 on a Red Sea kit today, I'm guessing likely due to GHA soaking up nutrients.

What are my next steps here? Little confused as where to go from here.

Time to get a clean up crew :)
