Ac70 50watt heater

[Bayou Reef]

Rena, jager or koralia? What will fit best and does it have to be completely submerged. My titanium died. Came home and tank was 98° so i trashed it. Everything survived, i'm impressed.

I have 3 Aqueon Pro 50w and really like it, compact size and been very reliable so far, almost a year. You can have it partially submerged up to the level mark which is about 1.5" below the top of the control knob, im using one in a beta tank this way.

I use a hydor theo 50w in my AC70. Works great. The whole thing fits under the lid, i just filed a little slot for the power cord.
