Chiller or AC for the room

[Lampshade]

I picked up a used 13000 BTU portable AC unit off craigslist for $100. I thought it would be great, but it draws 13 amps and blows the breaker all the time since it's the same as the tank is on. I put a window unit in the room that's a dinky little 5000 BTU unit, runs lots, but keeps the room at 78 and my tank stays fine at that.

Depends on the size of room you are in, I had a 10K BTU portable in my townhouse and it couldn't cool my tank because it was an open area design and was trying to cool the whole main floor. My tank now has a small fishroom that i can cool easially with a 5K BTU unit.
