Fluval tronic 300 watt beats the Marina hands down

[megatrev62]

Just picked up a tronic 300 watt used, primarily as a backup. Replaced the marina which was on bust (kept the tank at 82 degrees). Adjusted the tronic and has been a consistent 84 degrees with more to spare I would say. Having said that, it "feels" like a heater should. There is no big difference in price other than a few bucks. Just thought I'd shout it out for the tronic heater.

I have an old Tronic 200w that I use in a 65g aging water tank...it's bullet proof and holds temp really well.
