I recently completed my own DIY canopy for a 30 gallon tank. There isn't
much in the way of light leaks from my reflector (ahsupply 96w kit), so I
don't know if you'd really gain anything by painting the insides white and
having a reflector. That said, it's not going to hurt anything either. If
you have the paint all ready and don't mind dirtying another brush, I'd say
go for it.

Hi,

I have completed a DIY canopy for my 35gl hexagon. The canopy is made out
of pine and I am simply planning on staining it, inside and out. If
anyone
is interested I can post the DIY instructions for it. My plan is to
install
a 65 W retrofit kit into the canopy (including reflector). My question
is,
would it be better if I painted the inside of the canopy a gloss white?
As
this might aid in reflecting some of the light.... Or does it really
matter
and I can stain the whole thing.

Thanks

Reg
