I have a 37G open top tank.
My present heater is 100W Finnex. It was working well for a long time, but it can't get the temp above 70F now.
Glass heaters aren't what I want in there, too scary for me.
ViaAqua Titanium Aquarium Heater, 100W or 200W because I don't believe there are and 150W appx $45.
and the Finnex HMO-150 appx $40
Also I am not sure where each are manufactured. I emailed ViaAqua, to ask, just a little bit ago.
As a kid we had a catastrophic heater failure and it makes me very nervous when using heaters which could cook my fish. I tend to under size my heaters. :/
