Fe will help and I'd suggest it. Darker greens, faster growth after 1-3 weeks with good nutrients.

The saving grace for Cheato is that it can tolerant a wide range of conditions and still live and...

Yes, perhaps.

I think ideally, you'd have the fuge 1st, then post skimmer.

Good current, microbubbles in the fuge is still great though.
So having a wet/dry or a Berlin with a filter sock 1st,...

BGA here is not caused by excess NO3/PO4.

It's a new tank lacking NO3, assuming the test kit is correct.
You can change the water 2x a week 50% and still have BGA........

Aeration breaks up the boundary layers and adds CO2 for the weed to grow.

I think based on your system, and your past comments with cyano and others, that the Chateo is really NO3 limited..........removing more PO4 is not going resolve it either.

I'd try bottoming out the NO3 for a couple of weeks, macros seem not to like that.

It might affect the other tank inhabitants.
