Most of the consern is heat..
and using large sumps and Hot lighting is the big causes of this..
Using a return pump with just enough gph
to maximize filtration and using powerheads or larger pumps in closed loops will help..
So will using lighting like T-5 HO
rather then large MH
lighting units (If possible, tanks over 24 inches deep need MH
or Overdrivin T-5 outfits) Fans help alot with disapating lighting heat as well..
Im not so sure that insulating the stand would help (unless for some reason you were having cold tank issues.. wich would be odd to me..)
