Eheim Thermocontrol e 300 Heater

The obvious ideas are often the best. This also applies to the aquarium heating element. It is simply hung in the water and heats it up. The principle is the same as it was decades ago. But in the meantime, the EHEIM controller heater has become an ultra-modern thermal device. The temperature can be set precisely and is measured even more precisely and kept more constant by the electronics. The coating made of special laboratory glass increases the heating surface, serves as a heat shield and ensures even heat emission.

Precision, comfort, quality and safety "Made in Germany".

As you know, fish from tropical and subtropical waters need a certain constant water temperature. Before the engineer Eugen Jäger invented the aquarium heater decades ago, there was no really satisfactory solution to produce the appropriate water temperature. They dealt with complicated and sometimes curious methods. Some put the aquarium in the sun or by the heater or stove.
The EHEIM thermocontrol aquarium control heater is a further development of the legendary heating element and thermocontrol-e is the latest electronically controlled variant.
The temperature can be precisely adjusted from 20 to 32 °C. The control accuracy is ± 0.5 °C.
The heat is kept constant. A control lamp indicates the heating function.
The heater is absolutely waterproof, can be fully immersed, has dry run protection (Thermo Safety Control) and is suitable for fresh and marine water. One of the most important innovations is the glass coating:
• It increases the heating surface,
• compresses the heat, ensures optimum, uniform heat output and
• forms a heat shield (the aquarium inhabitants do not mind touching it).

The coating is made of special laboratory glass. This was created for research purposes. It is, therefore, free of pollutants that could be released into the water. Chemical and biological substances do not attack them. There are no cracks and hairline cracks through which condensation water could pass. It is impact resistant. And even extreme temperature fluctuations, such as those that may occur during water changes, do not affect this glass.

3.5, Not 3.0
Color: Medium Set of 6
These balls were almost exactly what I needed. I was replacing my boy’s favorite ball, which is the 3” squeaky, spikey ball that fits in the chuck it launcher. Unfortunately I saw the shiny object next to it and because there were SIX balls and a dollar less, I failed to see that these are 3.5” balls instead of 3”…. Great balls but no fitty in the slingy. Buyer beware. No chuck it no problem. Save a buck.

MY CHIHUAHUA LOVES THESE BALLS!!
Color: Samll Set of 8
My little chihuahua, BamBam, is addicted to balls, especially little balls that squeak! However, any balls that have material on them, BamBam will tear them apart, swallow the material and then get an upset tummy! These balls saved the day! BamBam LOVES them & she cannot tear them apart! They hold up so well! No matter how much BamBam plays with them, they keep squeaking away!

Squeaky ball

Perfect squeaky ball. Dogs love them. I love that they're durable and their thickness aids their durability. My Great Dane will play alone for hours with a ball.
