Finnex Titanium Aquarium Heater and Controller

Today we are taking a look at the Finnex TH-S 500W Titanium Heating Tube and Digital Controller Kit. I have had this aquarium heater for while and I love it. I provide a quick setup and review of this heating system.

I need that heater send it to me Jeff

Kari Kalender says:

Pick me! I live in a poorly insulated home and my temp swings are killing me .

Michael Marks says:

Apex + GHL temp probes can make me nervous, having two temperature readings + separate controller does seem safer

Greenstreet58 Lambert says:

Great heater and controller love the fact that the heater also serve as a ground probe.

Nice construction, titanium over glass any day!

James Wohler says:

Good stuff

Mike Crouch says:

Thanks for the info, I’m setting up a 125G w/ a 50G sump and still evaluating the options for heating. Having had standard heaters fail to shut off, I’m definitely leaning towards controller/heater combos; this video is extremely timely!

I likes it alot!

Martin Finn says:

My favorite heater

Andrew Lemoine says:

Great video Jeff I have that very heater would love a back up !!

Joe , Tropical depot says:

Need your help just bought this heater and it works . It’s a 300 watt in a 40 gallon breeder with a 20 gallon long is that a nought to heat it , I’m doing a test run right now and it’s been all most 2 hours and it’s only at 76 degrees?

T S says:

I have several of the bare heaters controlled by apexes but would like the redundancy of the controller.

However it says and you referenced a +/- 2 degrees. If I set it to 77 how tight to that does it keep the temp? 75-79 would be far too big a swing. Thanks

Patrick May says:

Would love a good standby heater

Mark Schmidt says:

I like the min/max feature and the auto shut off. For high watt heaters a separate controller is the only way to go.

Nathan Carter says:

Need one for my new tank build. Love premium aquatics..

oscar Anchundia says:

I would like to replace my current one with this one

carl rode says:

I have the finnex 500W and it is very reliable. This unit would make a great backup!

dwlee78 says:

nice. love that it comes with a controller.

Ian Mahoney says:

You said there was a 2 deg swing in temp, have you noticed multiple swings on your Apex?

Otto Reese says:

I’d be down to have this heater. 🙂
