When i got my Juwel rio 180 it came with one of these,

But it has no readings on it so i cant change the temperature of it. At the moment its about 30°c, Is this to high for my Neon tetra's and guppies?
Cheers chris

30°c is a little high i would say but it depends what you're reading the temperature from, if it's from one of them things that sticks on front of the glass i personally find them to show a little higher then normal, maybe someone who has that heater be able to help some more

These heaters are not marked afaik.

I think 1 click is supposed to be 1 Degree C, but dont quote me on that.

Just turn down a couple of clicks at a time, and see what the temperature ends up at. It may take 12 hours of so to show the new temperature.

30 is a bit high i think.

I keep my neons and corys at 25C, but do a google on the fish and find their preferred temperatures, then aim for somewhere in the middle of all of them.

Yeah if you scroll down a page or two it tells you about the heater.
