Question by: RT on Apr 22, 2016, 9:32 PM
Great question!
The length is 7.8" you will need 9" of clearance to handle the cable from the top.

Would 2 HMO-200 Finnex Heaters work for a 120 gallon reef tank?
Question by: Jeff on Jul 25, 2016, 6:44 PM
Hi Jeff,
The 200w HMO heater is good for tanks around 60-80 gallons and two of them would be perfect for a 120 gallon tank. Thanks for the question and if you have any more just let us know.

How long is the 100w? Would it fit in the back of an Innovative Marine Nuvo 20?
Question by: Rob on Aug 19, 2016, 7:24 PM
Hey Rob,
The 100w model measures 6.6" long and would certainly fit in the Nuvo 20.

Would 2 300w heaters work in a 215g? I figure with the rocks it prob. more like 200g of water? Also, can I lay them down flat on the bottom of the sump?
Question by: SB on Nov 25, 2017, 12:48 AM
Two 300w heaters may be a little underpowered for a 300g aquarium. It is hard to say exactly though without knowing the ambient temperature of the house, and a few other factors besides total water volume. You can always start with two heaters and then add a third down the line, or start with three and then if you only need two, pull one out to keep as a backup.
The Finnex heating tubes can be oriented in any direction.

Question by: Bill Peterson on Aug 21, 2015, 9:14 PM
Great question!
The Heater is 12" long exactly. However 13" clearance would be needed to fit with the chord coming out of the top of the heater. Feel free to let us know if you have any further questions!

Hello, I have a 120 gallon tank with 30 gallon sump and looking to update my heater. I wanted to add 2 but wanted both to be able to handle the tank is one is to fail. I see the measurements you provided and tank size but could you fill in the blanks for acutall length and area needed for these to fit ?
Question by: Jason on Jan 5, 2017, 6:35 PM
Great question! You can use the same chart listed on the HMX-S page for the measurements of the heating elements. Essentially they are the same length. :-)

Question by: Andrik on Apr 27, 2016, 2:11 AM

You will need between 550-1000 Watts in your system. 2x 300 watt heaters would work well!

I am starting a 55 gallon salt water. If I add a protein skimmer what size would I need? If I dont add the skimmer will the size suggested be to much?
Question by: Kathy Mitchum on Jan 16, 2017, 2:19 AM
Hey there! I would recommend a 200W heater for your size of tank. The use of a skimmer doesn't change the water volume of your tank, so no need to worry about including it in the sizing of your heater. :-) Happy Reefing!

IF MY TANK IS 60 GALLONS WOULD YOU RECOMMEND THE HMO-150 OR HMO-200?
Question by: PRESTON on Oct 1, 2013, 2:13 PM
For a 60g tank we would suggest using the 200w heater. Its best to err on the larger size in case you need it (say you have a particularly chilly day).
Answer by: Bulk Reef Supply on Oct 1, 2013, 2:13 PM
I have a 54 corner with sump. If I want to go with two heaters so one is a spare if one fails could I get one without controller as backup set low and the other with controller set-up? If this is acceptable what size would you recommend? Also do you recommend them in the skimmer section or pump section? Thank you.
Question by: Erik on Jan 18, 2016, 11:19 PM
Great question!
You can certainly select 2 heaters one which the controller set to a slightly lower temperature. For this size tank you will want 2.5-5 watts per gallon around 250 watt total. Here you could select 2 150 watt heaters to work well and place in the same section of the sump if needed!

Hello, I have a 15 gallon and 20 gallon tanks. Im thinking of getting the 50 watt for the 15 gallon but what should I get the 50 watt or 100 watt for the 20 gallon tank? Thank you -Paul
Question by: Paul on Mar 23, 2016, 5:01 PM
Great question!
Typically you will want between 2.5 watt to 5 watts per gallon. Ideally the 100 watt will work great with the 20 gallon tank. Feel free to let us know if you have any further questions!

I have a 92 Gallon Corner Bowfront with a 20 Long Sump and a 40 Breeder Frag/Refugium all plumbed together. Would you recommend 2 300 Watt heaters for this? Also, is the "controller" one that will kill the power to the heater if it gets stuck in the on "position"?
Lastly, what would you recommend for a 29 Gallon JBJ Nano Cube and would it fit in the back of the filter area?
Thanks!

Question by: Toby Robinson on Feb 3, 2016, 7:40 PM
Great question!
For the initial set up 2x 300watt heaters would work out great! The controller is the part which turns on or off depending on temp in the water column. For a 29 gallon tank we recommend anywhere from 75-150 depending on room temperature. usually 75 watt is plenty. Feel free to let us know if you have any further questions!

Do have a controller that controls both the heater and the chiller ??
Question by: ed Secula on Oct 7, 2013, 4:38 PM
Hey Ed,
For something like that you would be best served by an aquarium controller. The most basic of which is the Reef Keeper Lite unit and it will do both of those things as well as give you two more outlets you can use as timers or other functions.
