Question for Pony keepers?

[fishytime]

Im too far into it to turn back on doing the tank now(new sump and skimmer ordered for the big tank).....I was just trying to get a feel for what most pony tanks run at and if I need to think about some way of cooling just the add on tank. Thought of maybe doing an ice probe in the pony tank or possibly a kick butt fan blowing direct over the surface

Thanks for your help Kelly(here and at the other site)Was gonna start a build thread for it...just trying to think of a suitable title....Something like "the not so budget pony tank add-on"
