HI folks
I have been reading about small tank heaters, and just can't settle on one to try.
It doesn't help that I keep reading reviews for the few small heaters out there and some have real nightmare reviews! Others, usually ones involving a larger tank than the heater is rated for, are OK.
I am curious what YOU ALL think about the smallest heaters on the market... are they ever UL listed (especially the no-name ones sold on Amazon)? Can they indeed overheat and kill your fish? Which have worked for you?
