Just wondering... on setting up new heaters

[marie]

I have glass tops and metal halide lights on my tank and haven't needed a heater (or a chiller) since I set it up last may......temp stays between 79-82

[lastlight]

I'd never trust the built in thermostats. I use a ranco controller but even those are more than $100.

Had a few brand new heater that would never shut off & a few that where out by more then 5*. Thinking of trying the Oddyesea Digital or the Fluval E series digital to see if there any better.

I have 2 of the E300's and love them. I haven't had a problem yet and the one in my main tank is only 0.5 different from my thermometer (digital as well).

I pre-set/calibrate all my Eheim heaters in a bucket with a trusted thermometer and a powerhead
I set them to 81F just in case the controller leaves them on for some stupid reason, and I set my controller for 79F so the heaters will always come on

Where can I get one of these. Are they strictly for temp, with temp probe? $100 or so isn't bad.

I think you were reffering to these?

I have a dual stage so it can power a chiller or fans if it gets too hot.

your temperature fluctuate too much. Thats 3 degree and I am guessing between day and night. too much.

My temperature stay at 76 day and night. no fluctuation but I use a controller. 82 is quite high.

The most common failure for heaters is in the on position. And with 2 heaters you have just doubled your chances.

I have one tank with a heater, and use my Apex to catch it staying on. The other tank doesn't need a heater, and my chiller keeps the temp under control.

Both tanks have a max of 1 degree F variance, which I think is pretty good.
