Had a Betta Therm heating VP's bowl, and it was keeping it a nice and steady 80 degrees.
Doing my water changes today and had just put VP back in the bowl when the heater began to make this sort of buzzing noise and started to spew tiny bubbles from a single point on the unit.
Water fouled IMMEDIATELY and smelled like burning plastic. Rescued VP apparently unhurt, but he's in an unheated backup bowl until I can get another heater.
Anyone have a recommendation as to which betta-geared small heater is best? I'm not keen on ZooMed after this but I've heard good things about Marina's. Thoughts?
