Titanium with temp control on top of apex control, because my tank is in the garage with no insulation the temp drops pretty low so I use a 300 and 500w titanium the smaller one goes on first then larger if needed. The upside to a cold garage in the winter is a cool garage in the summer.

I see lots of people using the glass ones and while they're not supposed to be submersed, most people do and that is just a disaster waiting to happen, house fire all the way. Never happened to me but when sparks happen underwater it's just a matter of time before the cord catches and then boom. I had a stupid stealth before and the thing did exactly what I described above. The thing with glass is if it does explode I am worried about the glass shards in your sump and possibly getting electrocuted whenyou stick your hand in not knowing.
