I have a 40 set up w/dirt. Plants, misc cryps, ludwigia rep., compact swords, some vals, java fern, and some other stuff I cant remember. I put a Ray2 on top and started seening some hair algae. Moved it about 5" up and everything is doing great. No, I dont have rapid growth, just normal healthy growth. The ludwigia have kept their red coloration as well. I also have a Fuge ray on a similarly set up 20 b with the same results. I LOVE these lights.
I have the the Finnex FugeRay and I love it too! I also have many of the same plants you do. I've not had any algae issues though. Mine is mounted on the legs that came with it. I don't use a top so I'm getting full intensity. Great light.

Reason: misread the type of fixture
