So ,.. I would imagine that where you Doug and others live, heating must really be an interesting dilemma come winter time,...out here we do have our " cold" months where our nights and mornings may dip into the twenties but usually by mid day the temperatures will rise up to a balmy sub tropical 50., but the summer months is where it gets ugly and that's where the chillers earn their keep out here.
You said that your fire hydrant heater keeps it from getting " super cold"...,,knowing how you keep all your parameters in check and prob " spot on" ,I'm surprised that you have any temp dips in your system at all...my guess would have been a system developed by you that would maintain your temp from fluctuating year round.
On my little system I'm running a 500 watt heater combined with my cooler which between the two have been holding my system very constant,,( knock on wood )..HOWEVER,...we DO NOT have the constant icy ,bone chilling cold that you guys have to deal with on a daily basis,..... Gotta be really tough maintaining a tropical reef amongst such interesting conditions.
