Par reading and kelvin

[Proteus]

Colours are good growth is OK. I do find that some pieces ecrust lots but minimal vertical growth... I'm OK with the way it is. Just wondering if increasing par buy lowering light will help vertical growth. Light is on 6 hours a day.

Funny thing is that Coraline won't grow in upper 6" of tank

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.

I was thinking of lowering a little just to see reaction of acros. I have a deswalli that's at the highest par rating of tank and it grows fast. But colours are on the lighter end

Only way to tell is to try it

Yep. Thanks brad
