Coraline does best for me in my sump, with a tiny little light. I get almost none with MH. Which works out well, but I'd be happier if I could keep it out of my sump too
I think the light is maybe a bit high, but lowering it could raise heat and increase evap. If it's not too much trouble, try it for 3 months and see.
