is 77F the setting on your heater or it's the reading off the thermometer?HarleyK;4349142; said:Got them at 77F - how low would you go?

if it's the setting on the heater than the actual temperature could be higher when your lights are on, remember you have like 400W of lights right? that can increase the temperature of the water a bit.
You can probably go down to 75F, I know someone had a shoal of macs and he kept temperature at 75F (if remember correctly) to reduce aggression.
