I think it's too big not that it matters it will regulate as you said but imagine what will happen if it sticks ON

its not really about if its accurate, if the heater goes wrong, one thing that can happens is, it sticks on, such a big heater in a small tank, as andydrew says, will make fish soup in no time.

That kind of is a risk you are taking... I had a 300 watt in my 55 with no problems (which doesn't mean you couldn't have problems). Likewise, if the heater doesn't turn on in the tank for a couple days (say when you're out of town) then most tropical fish could die of temperature shock or develop parasites. All hardware has a risk.

300 watts? 100 watt would have been adequate for 70 liters.

i had a 300w juwel stick on in a 180ltr and it very nearly cooked my fish!!!!!!!!!!!!!!!!!!!!!!! so the same thing in a 70 would be fatal for the fish, 100w max, but better 2 50w.

I guess you just need to trust the thermostat.
