I have 8 .25 hp active aqua chillers and all working perfectly.. if you buy from vm innovations directly and not from amazon they have a coupon code for like 25ish bucks off also right now. All have been working great chilling between ~50 and ~100 gallons each, keeping them at 66-67 degrees with no difficulties.
Even if you don't need a .25 I would just get that over a 1/10th, it will run less often and has 3x the btus, the 1/10 are ~1000 btus and the 1/4 are ~3000 btus for only 75 dollars more, how that relates to cooling not sure exactly but considering its not much more money for at least double the water volume it will cool efficiently its worth it imo.
