Chiller recommendation?

[speedstar]

Have an IM-40 and looking for a chiller recommendation as the tank room does get to the mid 90's occasionally in the summer time. Everything seems to point to 1/15 or 1/10 HP, is anyone using anything bigger? I would prefer to but a 1/5 or 1/4 and be able to keep it for the next upgrade in tank size. thoughts and experience please

I repair chillers for some LRS. If me, I would buy a 1/4hp chiller and try to get the lightest one if possible. IMO

I use a 1Hp. Got it for $40. Amazing machine and will keep my 180 under 79 degrees in a 90 degree room.

When I can, I buy used chillers, never new. I like the lightweight ones.

I'm just worried that in a small 40g tank, you could drop the temp faster and farther below the setpoint with a oversized unit. Any thoughts
