chiller question

[foreverfortune]

i have central air, was considering buying a chiller to keep my temp down. but currently my tank temp is about 79 at the end of my 8 hour MH lighting cycle. i used 5 computer fans after i paniced when i saw my tank at 85-86 before the fans. i currenly have my house setting at 21 celcius.

i have never thought of buying a chiller before this incident but after putting 750w over my 92 gal i was worried that my ac would not pull the temp of tank down enough unless i sacrificed comfort/freezing the family. seems i managed to pull through though. i may still get a chiller just to be safe. and would like the house to be 1 degree warmer.

so it depends on how much you need to pull down, if only a few degrees then ac would be fine, if you need to drop your tank by alot then you would have to be living in a cold house to keep the tank down.
