With me having 5 tanks in my house i can confidently say that ive tested alot of diffrent heaters.

i recently had two 300w heaters(cheap chinese imports)in my oscar tank these were terrable as the temp setting very unstable jumping between 22deg C & 28deg C and almost impossible to keep a constant temp.

I went out to the LFS and bought a "Jager 3609" its a eheim product rated for a 600L to 1000L tank its fairly large(22inches),its got a calibration button on top of heater so you can keep it calibrated to perfection.

Ive replaced my two 300w chinese imports with this one heater and i can honestly say its the best heater ive ever used,i reccomend this product to anyone who requires a new heater.

This product is a bit exspensive,i paid $100 for it here,but its well worth the money as my oscars health is more important than a 100 bucks.

heres a pic of it

I've recently purchased a couple of these to replace crappy rip-offs that broke all too early, and I'd have to say I'd behard pressed to use anything else now. Temperature is absolutely stable, hasn't fluctuated once and we have had some really changeable conditions recently. Only down-side so far is they are so incredibly long
