So IMO give micro algae a go, You'lll find it can remove nutrients up to
10 times faster on average than most macros and is more stable and
provides a home for a larger quantity of inverts than the same area of
macro.
It's all good with micro algae.

Green hair algae is macro-algae too...
They call micro-algae only unicellular algae, green water.

You do not see people growing green hair algae for the risk
of introducing this stuff into the main tank - it looks ugly and
smothers delicate corals in your tank...
How do you keep hair algae to stay in your trays?
