For a Hagen heater, do I turn the black knob on the top clockwise or
counter-clockwise to lower it? If my memory serves, it didn't say on
the back of the blister pack it came in.

I've read online people saying to do it both ways. Thanks in advance.

Some one that is too freaking stupid to figure out how to adjust a
heater has *no freaking businesss fiddling with any critters that rely
on a human to keep in their artifical environment.......Some things
azre just too comp,icated for simple minded friggin idiots such as you.

Someone in The Freshwater Aquarium told me that in Europe they turn
the heater clockwise and that in th e United States counter-clockwise,
and befoe that, I turned it both ways and the heat went up one degree
for each, and it was 80 degree and one extra degree would be unsafe,
so I thought I'd ask in the hopes that I'd get an immediate answere
before I figgure it out myuself because it would take trial and error
and by then the temperature would keep on fluctuating which is
dangerous to the critters.

My idea is to buy a second thermometer (sp.) and put the heater into
another tank. I won't use the thermometer that's in the tank with the
fish since I have to be aware of any change in the temeperature. So
there.
