This test monitors the calcium level easily and precisely in steps of 20 mg/l (ppm) For approx. 7.500 mg (ppm) calcium. Add sera marin COMPONENT 1 Ca in case of too low Ca levels. A partial water change will help in case of too high levels.

Makes it easy to monitor the copper level in fresh and marine water Copper (Cu) is very toxic especially for invertebrates such as shrimps and crustaceans, but fish also react very sensitively to elevated copper levels. There are many possible causes for copper enrichment, including medical or algae combating treatments. The sera Cu-Test allows checking quickly whether fish or invertebrates are safe. sera aquatan provides help in case of elevated copper levels. Sufficient for approx. 50 measurements.

Makes it easy to monitor the chlorine level in fresh and marine water Chlorine is immediately removed by sera toxivec or sera pond toxivec. sera aquatan or sera KOI PROTECT make the water fish friendly. Sufficient for approx. 45 measurements.

Only the pHcontrol+e and power supply unit are included in the scope of delivery!EHEIM pHcontrol+e – the smart controller for monitoring and readjusting the pH value in your aquariumWith the EHEIM pHcontrol+e you can easily monitor and optimize the pH in your aquarium via a smartphone, tablet, or PC/MAC simply via a WiFi connection and your web browser. A pH sensor measures the current pH value of the water, and the pHcontrol+e automatically provides the necessary CO2 supply. By controlling the magnetic valve connected in series to the CO2 system it adds as much CO2 as required until the desired pH value is reached.To achieve this you must connect your CO2 system, i.e., a CO2 bottle via pressure reducer as well as magnetic valve (see the EHEIM CO2 sets) and a CO2 diffuser. The pHcontrol+e has a day/night control and can be linked to the lighting control EHEIM LEDcontrol+e (see the EHEIM DIGITAL family).In addition to light, nitrogen, phosphate, trace elements, etc., the plants in your aquarium need CO2 above all as an important nutrient. The better they thrive, the more oxygen they release, which the fish need to breathe. Thus, the EHEIM pHcontrol+e indirectly provides oxygen and the optimal pH value for your fish by adding CO2. This is usually between pH 6 and pH 8; pH 7 is considered a neutral value for reference.Note:The basis for measuring and stabilising the pH value is the carbonate hardness ("KH") of the water. Therefore, the EHEIM pHcontrol+e (in Smart mode) initially queries the KH value. Because KH, CO2 and pH value influence each other.Features of the EHEIM pHcontrol+eA smart controller for monitoring and controlling the pH value in the aquarium by regulating the addition of CO2.Includes Wireless WiFi connection with a WLAN-enabled end device (smartphone, tablet, PC/MAC).Has connection and compatibility with devices of the EHEIM DIGITAL family.Measures the pH value through the pH sensor (measuring range: pH 0 to pH 14).Control range of the controller pH 6 to pH 9.Needs to be coupled via pressure reducer with CO2 bottle (EHEIM CO2 set).Electronically controls addition of CO2 through interposed magnetic valve.Adjusts CO2 addition by linking with LEDcontrol+e (day/night control) in smart mode or simple and extended bio mode with own day/night control.Queries the KH value (carbonate hardness) in advance.Sets water test and calibration reminders.Guided calibrations of the pH sensor.Sends warning for deviation of pH value (up/down).Notes if EHEIM pH sensor needs to be replaced.Provides best performance, high power, stable connection, and large memory capacity through new improved chip generationHighest safety and reliability - 3 years warranty

Water testing for experienced aquarists Experienced aquarists check their aquarium water regularly. This allows taking measures, for instance against algae, quickly and easily, without the need to use chemicals. The sera aqua-test box contains the following test kits: pH value total hardness carbonate hardness ammonium/ammonia nitrite nitrate phosphate iron and copper or chlorine  

Makes it easy to monitor the ammonium/ammonia level in fresh and marine water Ammonium and ammonia mainly arise from fish waste. They are converted into each other depending on the pH value. While ammonium is mostly harmless, ammonia is toxic to fish. The sera NH4/NH3-Test allows monitoring the total concentration of both (the actual ammonia level can be calculated according to the pH value the using the included chart). In case of acute danger, sera toxivec (freshwater) or sera pond toxivec (pond) provide help. sera bio nitrivec (freshwater), sera marin bio reefclear (marine water) or sera pond bio nitrivec (pond) actively counteract lasting enrichment of these substances. Sufficient for approx. 60 measurements.
