Chiller for Smouse school tank

HI all,

The Smouse special needs school who got a tank donated last year at MACNA needs a chiller. Would prefer a 1/4hp or better since it gets up to 100 degrees in the summer. They shut down the HVAC during spring and summer breaks. This year I moved it to my house but lost half the coral. (oh yeah will be looking for coral in a ,omth LOL)Do not want to have to move it twice a year. They are on a very tight budget so cost is a huge conceren.

Let me know if you have one for sale or know where I can get one cheap. So far looks like 500 to 900 new.
