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
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!
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!

High quality build, but the thermostat is sub par By Garrett on 3/10/2017Garrett would recommend this product to a friendMy 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 3/3/2017brad would recommend this product to a friendThis 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 2/27/2017Gerry would recommend this product to a friendAs 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 2/24/2017Gino would recommend this product to a friendI 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 2/10/2017Jorge H. wouldn't recommend this product to a friendI 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 2/6/2017Matt would recommend this product to a friendAbout 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 2/4/2017Pierre would recommend this product to a friendUsed 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 1/6/2017rob would recommend this product to a friendI 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.
Heater is good but too long By Tony on 12/30/2016Tony would recommend this product to a friendI have used these heaters in the 200w for many years, but recently I upgraded to a new sump with baffles... And the heater won't fit anymore. Most heaters in the market arent this long. They're good but too long!!!
Great heater By Sunmonkey on 12/19/2016Sunmonkey would recommend this product to a friendGreat heater, agree with another reviewer that they are sometimes too long for their ratings, but otherwise excellent. Should have bought this heater first.
Great heater By Bryan F on 12/12/2016Bryan F would recommend this product to a friendThis heater does what it was designed to do. I have two of them currently running, one on a ~110 gallon reef, the other on my water mixing station. I have not had any issues with them and do not plan on replacing them with a different heater.
This Heater Rocks By DrChop on 12/8/2016DrChop would recommend this product to a friendSince setting up my 28g nano, I have been fighting temp fluctuations all day every day. I bought a 100w VA brand when I bought the tank and it was never even close to accurate. Decided during the sales of Black Friday to get a 125w Eheim and it has been the best decision. After looking at the flat one from another manufacturer I saw at Palooza, I decided on this one instead. Reviews were pretty solid and I know they have been a solid brand over the years. Now, my temps might move about 0.5 degrees between day and night. I don't have to keep fans on the tank, adjust the temps, or anything. It just works and holds true temps. Word of advice: Don't Cheap Out On The Heater!!
