Hey Francis, does it look like it can be cleaned inside since it serves as the filter intake? Also, when doing WCs, how much of the filter must remain in water, if any? Looks like a pretty large light too (is it?) and a flashing light for abnormal temp is a great idea! I hope it works well, awaiting updates. Maybe this is a heater that should be stocked in Connie's Fish Store in the basement?
BTW went shopping in C'sCS in the basement and came up with the Olympus Stylus 1010 which I'll have on Friday. I'll be able to take pics again (once I figure it out, that is)!
