peltier cooler

[badsekktor]

place the aquarium in an air conditioned room maybe?

That is what i thought at first. Problem is if we keave the house and turned the aircondition off. The sudden drop in temp might kill the fish. I tried placing a simple cdrking fan and at night the temp drops to 26 deg and comes up to 28 at noon.

I've read somewhere that peltier coolers might lower the temp too much and kill the fish when not monitored.

will be trying a couple of fans and observe first before trying the peltier cooler.
