JBJ introduces the TRUE TEMP digital heater controller and titanium heating system. The TRUE TEMP is the most complete heating system to date with the most advanced features that set it apart as the leading heater for professional hobbyists.
Our digital microprocessor boasts amazing +/- 0.5 F accuracy, a calibration setting, indestructible titanium heating element with thermal shut off, smart memory chip, LED heating indicator, safety guard, remote temperature probe, and a large constant LED display of the current temperature.
Maintaining the correct temperature for tropical fish may be the single most important factor for a successful aquarium. Since fish do not have the ability to regulate their own body temperature, it is crucial that we can provide consistent water temperatures with minimal fluctuations.
Majority of fish cannot cope with stress from constant temperature fluctuations, which leads to a compromised immune system. This increases the probability of avoidable diseases, parasites, and bacterial infections.
ADVANCED FEATURES:
100% DIGITAL OPERATION Don’t be fooled, some controllers still incorporate analog dials and knobs without the precision accuracy of TRUE digital controllers. Our advanced microprocessor constantly reads and displays the correct temperature to a tenth of a degree with a large LED display. Easy push buttons make setting your desired temperature simple and easy.
TITANIUM The perfect submersible element for fresh or saltwater aquaria. Virtually indestructible with the benefits of fast heat transfer without any corrosion. Integrated thermal shut off and out of water safety mechanism.

TT-1000 1000 WATT 16.7” X 1.5” 6 FEET 200 - 300 G
REMOTE TEMPERATURE PROBE Most heaters have an integrated temperature probe within the same heating element. This can lead to false readings and premature ON/OFF cycles. The TRUE TEMP digital controller is equipped with a remote quick disconnect temperature probe that can be placed up to 5 feet away from the heating element for a comprehensive temperature measurement of the total volume of water. Quick disconnect temperature probe grants easy replacement without the need to replace the entire controller in the event it fails.
SAFETY GUARD All titanium heating elements are securely placed inside our safety guards that protect you and your livestock from the heating core. Our flow thru design grants continuous water contact without interruption.
CROSS REFERENCE Have you ever noticed that majority of heaters cannot be calibrated. Often times, errors do occur during the calibration process. The ability to cross reference ensures your temperature is accurate and always correct.
SMART MEMORY CHIP An integrated smart memory chip will restore the previous temperature set point and calibration to the last stored setting once the power returns after a failure. This alleviates having to manually reset settings forever.

Worked great for 14 months and then stuck on and over heated the tank. The digital display read out 75 and heating, but the heater was heating the tank to above 86. No response from JBJ.
PROS
Great for sumps, checks incoming and heats on outgoing
CONS
probe doesn't last long enough, no warning when probe goes out.
REVIEW
Worked good for about a year. Love the design of being able to check the temp on my incoming water into my sump, and heat the water going to the display. Probe went out, called JBJ NO HELP, CS acted like i was bothering them. They don't sell probes on their website, had to get one off of Amazon.
Installed easily in my 30 gallon tank-heater at mid depth on left side and probe directly opposite at same level. I set at 78 and it fluctuates perhaps 1 to 1 1/2 degrees on digital readout, occasionally to 2 degrees. An independent thermometer check leads me to believe that I'd be chasing a ghost t...Read More
Installed easily in my 30 gallon tank-heater at mid depth on left side and probe directly opposite at same level. I set at 78 and it fluctuates perhaps 1 to 1 1/2 degrees on digital readout, occasionally to 2 degrees. An independent thermometer check leads me to believe that I'd be chasing a ghost to correct it. In use just 10 days now and corals flourish and invertebrates and single urchin, anemone, and Maroon Clown all fine.If all stays same I'm very satisfiedHide
