Product Questions

Hi,

I want to purchase a water heater for my RODI water while being mixed with salt in preparation for a water change. In other words to throw in the bucket for QUICK heating. What heater is best for that? Thanks
Question by: Reggie on Dec 5, 2016 9:48:00 AM
Great question! For the purposes of quickly heating your water, the larger the heater the faster the process. In which case, if you have room for larger heaters then get the largest that will fit. :-)
Answer by: Randy (Admin) on Dec 20, 2016 3:39:00 PM
Hi there - I'm trying to decide between these and the Finnex heating element (both would be hooked up to Apex) - and wondering why the wattage ratings are so different? For instance, the 300watt of this version is rated for a 250+ gallon tank, whereas the Finnex calls for 800 watts for the same size tank. Watts would seem to be watts, so just wondering if these are that much more efficient than the titanium versions? These would be going on a 500+ gallon total system, so trying to be as efficient as possible. Thanks, Peter
Question by: Peter Tucker on Jan 24, 2017 10:41:00 PM
Great question! It will definitely tank more than a single 300W heater for that size of tank, so in the mindset of efficiency, you will want to look at the 800W heaters. I would recommend at least 2-3 heaters for redundancy and efficient heating. :-)

I bought one for my 6 gallon JBJ. I'm having issues fitting it in. Can the heater be touching anything in the aquarium?
Question by: Jessica on Jan 25, 2017 8:02:00 PM
Hey there, great question! Most acrylic tanks can stand up to the intermittent powering of the heater, as far as not melting. With glass tanks and baffles, there is no issue at all with the heater touching those edges. :-)

Can the heater be laid down in a sump tank
Question by: Charles Graham on Apr 6, 2016 8:54:00 AM
Great question!
The heater could be laid down in the sump. Under full details the length of each heater is supplied. Feel free to let us know if you have any further questions!

Hi, I'm planning on buying 2 of these heaters. 1 will be my backup incase first one fails. What wattage should i get for a 120 gallon tank 48" x24" x24"?
Question by: Brian Beaulieu on Feb 3, 2016 3:01:00 PM
Great question!
You will want a minimum of 2.5 watts per gallon up to 5 watts per gallon. Overall on a 120 gallon you will need a minimum of 300 watt heater. Feel free to let us know if you have any further questions!

  • My go to heater By JcSH2o on 5/23/2017

    Absolutely without a doubt my go to heater. Easy to calibrate, dependable to use. I would 100% recommend this to anyone.
  • Reliable By Terrence on 5/21/2017

    I like this heater. I use a 300 watt Jager and find that it does a good job of heating my tank and is reliable. Good price here at BRS as well.
  • this is the brand I use By Gary Majchrzak on 5/5/2017

    TIP: Split required heating wattage between two heaters and run them on a controller
  • Awesome By Mark on 4/27/2017

    Extremely stable temperature. Works better than expected, and really easy to calibrate!
  • High quality build, but the thermostat is sub par By Garrett on 3/10/2017

    My Jager never was able to run without a 4 to 6 degree fluctuation, so I had to get a thermostat and not use the sub par thermostat. However, it is built very nicely, so once I got a thermostat, I had no problems. This is not a deal breaker because most heaters should be run on a reliable thermostat, anyways, to avoid failure.
  • Solid heater By brad on 3/3/2017

    This heater is spot on after calibration. I use one in my sump and I have another one I use in my salt mix container. Always spot on
  • High Quality By Gerry on 2/27/2017

    As I unpacked the 300W Large Heater, I was worried damage had occurred during shipping. To my delight, I saw the packaging ring had done its job with three broken prongs, but no damage to the Heater itself. It came preset to 79 degrees F and after 48 hours I checked it with my Fisher Scientific Thermometer to be accurate within 0.2 degrees. I am satisfied with the purchase and will probably buy another one in the near future.
  • Works well... reliable and price is reasonable By Gino on 2/24/2017

    I have four of these heaters... two in my sump which are controlled by my Apex system... one in my mixing tank (just using its own thermostat)... and another that is a spare except for when used in a quarantine tank. The ones that are controlled by the Apex keep the temp within 0.2 degrees F. The one in the mixing tank reads a bit low (i.e. the water is slighter warmer than the setting on the dial when checked with an external thermometer... but works fine) I have the same complaint as others however... they are fairly long and you need a larger sump for them to fit nicely.
  • What a waste !!! By Jorge H. on 2/10/2017

    I hate this heater my QT tank heater from Petco is far more accurate than this junk, on every setting I wait 12-24 hrs for re-adjustment and it fluctuates 2-4 degrees, I had it set to 78 24hrs ago and this morning water temp at 82 and claiming so I re-adjusted and lowered to 78 again waited 1hr and the thermostat still is on so I lowered again some more and forgot about it and went to work, so I am hopping I don't get back home to a aquarium full of dead fish.
    This should not be so complicated for a simple heater and for less than $30.00 you have the risk of loosing everything.
  • Great heater for the price By Matt on 2/6/2017

    About a year ago I went through several heaters before stumbling upon the eheim jager trutemp. I purchased a brand new 200w jager trutemp for my 75g reef tank and I was having problems with the heater fluctuating temps drastically. After emailing the manufacturer they promptly sent me a brand new replacement and I've been using it every since!
  • Great Heater By Pierre on 2/4/2017

    Used in Mixed Reef 120G, Temperature variation of ~1F using my Apex Controller, no problem and work as intended. I wish they had a shorter design as it can be challenging to find a good spot for a 18" Heater. -1 Star for the length.
  • Great product By rob on 1/6/2017

    I really like these Jaeger heaters. They work well and are dependable. Simple to use. I never have any problems with them. When I worked at a LFS, that is all we used.
