Simple yet effective ideas often yield the best results. Take the aquarium heater, for instance, designed as a rod that hangs effortlessly in the water to provide warmth. While the basic principle has remained unchanged for decades, significant advancements have occurred since then. The EHEIM adjustable heater is now a state-of-the-art electronic thermal device equipped with the latest technology. Its jacket, crafted from specialized laboratory glass, enhances the heating surface, acts as a heat shield, and ensures optimal, uniform heat distribution. Whether you need to heat a 20-liter or a 1000-liter aquarium, you have 9 sizes available to choose from.

Advantages of the EHEIM thermostatic heaters:

  • Accurate temperature adjustment from 18 to 34 °C
  • Easy and secure recalibration (±2 °C)
  • Temperature control precision of ± 0.5 °C
  • Maintains a steady heat level
  • Heating function indicated by a control lamp
  • Fully submersible (watertight)
  • Automatic dry run shut-off feature (Thermo Safety Control)
  • A glass jacket enhances the heating surface and guarantees optimal heat distribution
  • Convenient cable length of approximately 170 cm
  • Includes double suction cup holder
  • Nine sizes suitable for aquariums ranging from 20 to 1000 liters
  • Appropriate for both fresh and marine water

Precision, user-friendliness, quality, and safety — all “Made in Germany.” The EHEIM aquarium heater represents an evolution of the classic heating rod. You can precisely set the temperature between 18 and 34 °C and calibrate it if needed (±2°). The temperature control accuracy is ± 0.5 °C, ensuring consistent heating. A control lamp indicates when the heating function is active. The rod is completely watertight, can be fully submerged, and features an automatic dry run shut-off (Thermo Safety Control), making it suitable for both freshwater and saltwater environments. A key innovation is the glass jacket, which:

  • Expands the heating surface
  • Concentrates heat for optimal, even distribution
  • Acts as a heat shield (safe for your aquatic life)

The jacket is made from high-quality laboratory glass, designed for research use, ensuring it is free from harmful pollutants that could leach into the water. It is resistant to chemical and biological substances, and its construction prevents any fissures or cracks that could allow condensation to infiltrate. Even significant temperature changes during water changes will not harm this durable glass.

I LOVE this sunscreen!! Super affordable and lightweight for your skin!
Size: 6 Fl Oz (Pack of 1), Style: SPF 50
I love this sunscreen!! Love it so much I bought 3 bottles of it! Super lightweight and blends right into the skin, and I don’t feel not sticky! I got super excited and got this primarily because it’s lightweight, super affordable, SPF 50 for high protection, and it said there’s no alcohol or fragrance…heres the catch tho, there IS a slight sunscreen smell, but you only notice it when applying it and if you keeping smelling it on yourself up close during the day. Other than that, it’s truly fragrance free in the sense that you aren’t just standing there doing your thing, and keep getting HIT with the scent of sunscreen for hours, like other sunscreens! The scent is extremely light and pleasant when you go to smell it on yourself. Don’t EVER discontinue this please please please!!!!

It’s great! So light weight!
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
I have been testing this out for a month now. I love it. This does have avobenzone in it, and because of that, I do NOT put it around my eyes as avobenzone is a chemical sunscreen ingredient that typically tends to cause the of sensation of burning eyes! At least for me it does. I use an Australian sunscreen around my eyes that doesn’t have anything that irritates my eyes. So for the rest of my face, this stuff is great. It literally is so serum like sinks into your skin within five minutes or sooner. Now it’s not the most hydrating thing in the world so if you have a dry skin, you still wanna go in with a moisturizer before however, if you have oily skin, this is your girl right here. Skin like finish, not super matte and not dewy at all. I do not wear primer so I don’t know how it plays with that. Works great under my makeup and has never caused pilling. Quick, easy, simple ingredients, definitely sensitive skin friendly, and no fragrance at an affordable cost-effective price! Now if only banana boat decided to go cruelty free😭 9/10 bc not CF 💔

Great sensitive skin sunscreen
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
Love this! I have sensitive skin. this did not sting my eyes, or burn my cheeks. Left no white cast. I'm not noticing any scent. It just feels like bare skin, it's not heavy, drying, oily or sticky. No pilling. Went on smooth, not streaky, looks like skin once dried down, not patchy. I hope they keep this in stock forever!

Lightweight and Effective
Style: SPF 70, Size: 8 Fl Oz (Pack of 1)
I love how lightweight and comfortable this sunscreen feels on my skin. The appearance leaves a nice glow without looking greasy or heavy. The bottle size lasts a long time and it’s very easy to apply evenly. It also smells amazing compared to other sunscreens. Definitely worth the money and perfect for everyday use.

Good!
Style: SPF 70, Size: 8 Fl Oz (Pack of 1)
Works well! Love the subtle shimmer and glow it gives me. Doesn’t leave a white cast, but definitely does feel a little oily on the skin. Smells very nice too, not that classic chemical sunscreen smell at all.
