For the safe stabilization of water values ​​- it prevents fluctuations in the pH value For gentle and reliable increase of carbonate and total hardness Increasing and stabilizing the pH value It reliably prevents dangerous pH fluctuations ("acid shock") Natural processes inside the lake, as well as downpours, strongly influence the carbonate hardness and pH value. Which can lead to life-threatening pH fluctuations. sera pond bio balance increases the carbonate hardness as well as the total hardness in a natural and gentle way and therefore stabilizes the pH value in the long term. sera pond bio balance ensures a balanced supply of minerals, reduces stress and optimizes the living conditions for fish and plants.

With the EHEIM thermocontrol-e heating element your fish get the right temperature even more precisely - in every aquarium. 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. And whether you want to heat a 20 or 1200 litres aquarium - you can choose from 10 sizes.Advantages of the EHEIM control heater thermocontrol-ePrecise temperature adjustment from 20 to 32 °CNo readjustment necessaryControl accuracy ± 0.5 °CThe heat is kept constantControl lamp indicates the heating function (red: heating up; green: temperature reached)Fully submersible (waterproof)With dry-running protection (Thermo Safety Control)Glass coating increases the heating surface and ensures optimum, even heat outputConvenient cable length approx. 170 cmIncluding double suction holder10 sizes for aquariums from 20 to 1200 litresSuitable for fresh and marine waterHighest safety and reliability - 3 years warranty Precision, comfort, quality and safety.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 a 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 it. 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.Diameter Ø:36 mmHeight:496 mmPerformance at 50 Hz:400 WattMax. temperature:32Sea water:YesMin. temperature:20 Freshwater:YesPacking:6 Part (s)For aquariums up to approx.:1200 LiterFor aquariums of about.:1000 LitersManufacturer guarantee:3 Year(s)

These high performance hang on protein skimmers are designed for use by hanging on the rim of your fish tank.Protein skimmers have a fairly simple design but achieve a very important task in your aquarium. Each protein skimmer comes complete with a submersible needle pump, which utilize needle-wheel technology for the finest bubbles. The surface tension from these bubbles attracts organic waste and carries it through the column; then it's "skimmed" into a collection cup for removal.All of our protein skimmers come with a needle wheel venturi pump included. This type of pump introduces air via the venturi air pipe and as the water is drawn through the needle wheel impeller it chops the incoming bubbles into a fine mist. Leading to a greater performance skimmer.Please ensure skimmer outlet pipes are fully submerged for unit to run correctly. Water level must be no lower than the maximum depth from rim listed below. Suitable for sump use (as a hang-on).

Introduction to use: 1.Do not submerge the air pump into the water. 2.Air pump must be placed above water level. 3.Do not oil at any time. 4.Disconnect the plug if the pump fails. 5.Clean or replace air tube or air stone regularly to obtain maximum aeration and longer life. Important Safeguard: Disconnect the plugs of the electrical aquarium appliances before putting hands into water. We recommended that air pump and other electrical aquarium devices, should be connected to power supplies with ground fault circuit interrupters.
