Another beautiful mangrove tank. Thanks for sharing.Thanks for the reply the reason I ask is there was a pictures posted on a previous page that had the tank in the window, but a light below the leaves. Typically with plants you want the light on the leaves so I wasn't sure if these were somehow different. I assume this light was for the other Macro algae than.
Your system (very nice btw) looks too far from window. Can not hurt to try though.
Mangroves can be incredibly slow growers. I have to add iron to enhance growth.
