Chiller size for frag tank?

[IOnceWasLegend]

So, I'm looking into the wonderful world of aquarium chillers, and trying to figure out how to properly size a chiller for my needs.

I'll have a 50g frag tank, a ~30 gallon sump, which will both be in an uninsulated garage in San Jose under MH/T5 lights. I think I'd need a 1/10th HP JBJ chiller, but want to make sure I'm on-base with my guess so I don't over-engineer this *too* much. Thanks!

It will be enough..i was running 1/10 on my 150g for years.

But if it's in an unregulated garage, i would move up to 1/4hp

If you use fans as well 1/10 will work fine pretty sure

It will be ok. As Mike said. Maybe couppe it with fans and u should be good.
