What is your temperature fluctuation? This can be the cause of stress for the corals and fish, and is normally what initiates ich IME.

mine don't flucuate much at all....usually around + or - 1 degree...the 120 has run this warm since we first put it up...strange!

I didn't use one for the past two years (no chiller either, just temp comtrolled fan) but now I use a couple in the winter cause I let the temp get below 15 in the house at night.

I'm considering putting mine on a timer and only having it come on for 6-8 hours at night. Would this be objectionable in any way?
