Calibrating your Eheim Jager Heater

The reason Jager heaters have a reputation for being the most accurate heaters available is the ability to recalibrate the heater.

The factory setting should be reasonably close but if you moved either the red arrow or the blue dial before reading the instructions you may need to recalibrate the heater.

  • Features a shatterproof glass construction
  • TruTemp dial adjusts from 65° to 93° F
  • Thermo safety control enables 'running dry' protection
  • On/off indicator light verifies heater functions
  • Includes mounting bracket and suction cups
  • Simple and safe recalibration (±2 °C)
  • Generous 5.6 foot cord

Eheim Jager TruTemp Submersible Heater

300 Watts

Precisely regulated, constant water temperature is very important for the comfort and success of your aquarium inhabitants. The Jäger TruTemp adjustable heater is an ultra-modern electronic thermal device offering today's best technology. Designed for use in both freshwater and saltwater aquarium, Jäger TruTemp fully-submersible heaters include these great features:

Shatterproof glass construction - Made with laboratory-grade glass, TruTemp heaters are free of pollutants, resistant to chemical and biological substances, and able to withstand extreme temperature fluctuations. Their glass jackets also enlarge the heating surface and ensure even heat distribution.

TruTemp Dial - Temperature can be precisely adjusted from 18° to 34° C (65° to 93° F). Using the TruTemp dial with readjustment ring, the user can recalibrate the heater for a precise temperature reading. Control accuracy is +/- 0.5° C.

Thermo Safety Control - This safety mechanism enables 'running-dry' protection. The heater will shut off when removed from the water, and resume functioning upon return.

On/Off Indicator Light - This convenient feature eliminates guessing and enables the user to verify heater function without getting their hands wet!

Each Jäger TruTemp Heater also includes a mounting bracket and suction cups for secure and flexible placement within your aquarium system. Lastly, an extra long power cord accommodates most applications.

Dry Skin Miracle!
Size: 8 Ounce
I have very dry skin, and around my chin and nose, it flakes and turns red, exposing my inner layer of skin due to severe dryness. I could never seem to hydrate it or get rid of the flakiness. I thought it was just my skin at this point, and I could do nothing to solve it. Now, I've never considered using Cerave; I've always heard negative things about it. However, I've never been a makeup person until now, when I want to try to elevate my look (not to mention I'm always in pain from a lack of hydration). The problem is, my skin is so dry that it cracks the makeup, preventing it from setting well on my face. Another problem is that around my nostrils, the flakiness looks like boogers, nasty. It's incredibly annoying. So I did a little research, and now I'm here. LET ME TELL YOU! This cream is amazing! I love how thick it is, and how a little goes a long way! My face, for the first time in my short life, is not dry! It's not buttery smooth, as in your hand won't glide against my face, but it won't feel the flakiness and roughness of my skin—and that's a game changer! I'm genuinely obsessed with randomly rubbing my face to feel the almost barrier of hydration, especially around my nostrils! I cannot explain the level of amazement I felt when I touched my nostril area to feel practically smooth skin. I felt as if it were a miracle. I've only used it for a week now, keep in mind, and this is how I feel. PLEASE BUY THIS IF YOU'RE LIKE ME! I'M SO HAPPY WITH THIS PURCHASE, AND IT'S WORTH ALL MY MONEY 🙏

If you use tretinoin this is for you!
Size: 8 Ounce
This moisturizer has been a total game changer for my skin. I’ve been using tretinoin, and my skin became extremely sensitive—dry, irritated, and compromised. After adding this cream into my routine, I noticed a huge difference. It helped restore my skin barrier, and my skin feels calmer, more hydrated, and much less reactive. The ingredients are simple and gentle, which is exactly what sensitive skin needs—nothing unnecessary or irritating. I’ve tried much more expensive moisturizers, and honestly, I would pass on them and stick with this. It performs better for me without the high price tag. I also love how versatile it is—I use it on my face, neck, and body. It’s rich and nourishing without feeling greasy, and it absorbs beautifully. If you have sensitive skin or are using tretinoin, this is definitely worth it.

Effective and wonderful-smelling body wash.
I am picky about body wash, especially fragrances, and this one is one of the best. First and foremost, Method is a eco-friendly brand of bath, body and cleaning products that include non-toxic ingredients and no animal testing. Those things are important to me about a brand. This Simply Nourish body wash includes shea butter, rice milk and coconut to soften skin. The scent is very light and soothing - think a little hint of vanilla, lavender and powder. The scent doesn't linger on your skin or interfere with other fragrances you might use - it just smells really great in the shower. No residue left on the skin, just smoothness, cleanliness and softness.

Outstanding, lightly moisturizing, clean product
Moisturizing, but light...not heavy. Smells like rich, real coconut, but again...not heavy. Lathers well and leaves not residue on skin. I really like the Method body washes and have a bunch of them which I rotate based on the scent I'm in the mood for. This is one of my favorites.

Strong Clean with a Gentle Feel
My husband has been looking for a body wash strong enough to handle the dirt and residue from blacksmith work, but still gentle enough not to dry out or irritate his skin. This product checks both boxes with ease. Quick verdict: Cleans extremely well, lathers easily, and despite being tough on dirt, is still gentle on the skin. ✅ What we liked: -Effective cleansing. Easily washes away dirt and grime without needing excessive scrubbing. -Rich lather. One pump creates plenty of foam for a full-body wash. -Thick gel consistency. A little goes a long way, so the bottle lasts. -Lightweight formula. Doesn’t feel greasy or heavy on the skin. -Gentle on skin. No irritation was noticed with regular use. -Clean ingredient profile. Plant-based, free from parabens and phthalates. -Fresh scent. Cool, crisp fragrance with light menthol/mint notes that aren’t overpowering. -Scent lasts even when the shower ends. -Cruelty-free. Not tested on animals. ⚠️ Things to consider: The scent has notes of menthol and mint, which may not be for everyone. Best for people needing a deeper clean (work, outdoor, hands-on jobs). Great for daily use without drying out skin. For anyone who likes a fresh, light minty scent. Overall, this has been a really great addition to his routine. It performs well for heavier-duty cleaning while still being gentle enough for daily use, which can be hard to find in one product. ⭐️ I included a video showing how much lather you get from a single pump, along with a photo of the consistency for reference.
