Question by: lisa on Sep 9, 2015 2:49:00 AM
Great question!
2x 300 watt heaters would be a perfect set up! Feel free to let us know if you have any further questions!

How long is the 300W heater?
Question by: Bill Peterson on Aug 21, 2015 4:14:00 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!

IF MY TANK IS 60 GALLONS WOULD YOU RECOMMEND THE HMO-150 OR HMO-200?
Question by: PRESTON on Oct 1, 2013 9:13:00 AM
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 9:13:00 AM
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 5:19:00 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!
Answer by: Connor (Admin) on Jan 27, 2016 1:45:00 PM
Do have a controller that controls both the heater and the chiller ??
Question by: ed Secula on Oct 7, 2013 11:38:00 AM
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.

  • Awesome heater By Erik on 1/21/2016

    Love this heater have had multiple for different tanks. Keeps the temps nice
  • Works good By Andrew on 1/17/2016

    Bought the 300 and it works pretty good about 1 degree off. I've had it only for about 2 weeks. One of the better heater companys
  • Almost Great By Chris on 1/3/2016

    I haven't had great luck with any heaters since the early 2000's. So far I like everything about this heater. It's consistent, easy to use, and priced well. It is at the edge of the 2 degree tolerance, but I monitor so it isn't a huge deal. I wish the temp probe was separate still, but it works. Will buy again.
  • Quality product, reasonable price By Paul on 1/2/2016

    I have had the heater for around 3 months and it has worked perfect with minimal temperature fluctuations. The unit has quality construction and the external controller with temperature display is easy to use and looks great mounted in my sump.
  • Great product By Witzi657 on 12/15/2015

    Bought 2 for my 135 and keep them in the sump. Temperature barely fluctuates.
  • 300 watt finnex By Jeff on 11/25/2015

    I use this product with my reefkeeper and am very happy with how it's setup. The separate display is very helpful for knowing when the unit is running or not so I can monitor any temperature swings. The heater itself is a very good size, and does not stick out of my sump the way my previous 300-watt heater did. This was a great buy for my needs. Thanks BRS!
  • Average By Kev on 8/2/2015

    Suction cups for holding heater in place do not do the job at all.
  • Great Heater By Donna on 7/19/2015

    I'm really impressed with this heater. I've been using it for about 3 months now and it doesn't miss a beat. Just set it & forget it, no more temperature swings. Also love the fact that you can adjust it without getting your hands wet.
  • Great Heater By Kristoffer on 5/28/2015

    I have gone through about a half dozen different heaters on both my 75g reef and 20g reef. This heater is by far the most reliable and consistent heater I have owned. It always maintains water temp with a +/- of 1 degree. I absolutely love this product..
  • 300W of power By Terri on 5/4/2015

    The 300w has changed-there is no separate temp probe, it is now located on the unit. The older model worked fine keeping the temp stable so I will need to see how this new method works. So far, the temp is rock solid. I like these heaters because of the ease of setting the temp and there is no glass to break.
  • The best heater I have used! By Alex on 5/4/2015

    I love these heaters, I have now bought 4 for different tanks and want to get them for the rest of my tanks too... They have a digital readout at all times telling you the current temperature. You set the temp you want it at and it automatically keeps it there, you know when it's on because a red light lights up. The other thing is they are not glass and feel so much sturdier than glass ones. I will only use these from now on, live it!!!
  • Dangerous By Kevin on 4/15/2015

    Two out of three went bad. I went to clean the inside of my tank and got a nice little zap I unplugged the heaters one at a time and then tried them all individually two shocked me.
