This will be my first time purchasing an Hydor ETH 300W inline heater. Would one Hydor ETH inline heater 300w be enough to keep a 150g 5'x2'x2' with snug closed top steady at 80F? what are the good and bad of this Heater? I planned to run this on my Eheim 2028 Pro II with full media.
Is the Rena Smart Heaters a better option?
