Looking for 1/4HP or bigger chiller

[Marlin65]

I have a Aquatronics chiller that I just had recharged, but it is only 1/5 HP and does not pull my tank down enough.
(150 gallons total system in a hot room.) So am going to need an upgrade. Looking for a bigger one and willing to do a trade if you want a smaller one.
Let me know if you have something?
If someone wants to just buy the 1/5 HP $200.
Will post some pictures later.
