An advanced technology that merges rapid performance with precision for optimal aquarium and pond water testing results, all in just two minutes. Analyzes various parameters such as: nitrate, nitrite, ammonia, phosphate, carbonate hardness, general hardness, pH, magnesium, and calcium.

Facilitates the tracking of pH levels in both freshwater and marine environments, including ponds. Suitable for approximately 100 tests. If pH levels are found to be too low, we suggest using sera KH/pH-plus for freshwater aquariums or sera pond bio balance for pond applications. Conversely, if pH levels are too high in freshwater aquariums, we recommend either sera pH/KH-minus or filtering with sera super peat. For detailed usage instructions, please visit this link.

For the effective stabilization of water parameters - it helps to prevent fluctuations in pH levels. It gently and reliably enhances both carbonate and total hardness while also stabilizing the pH value. This product effectively guards against hazardous pH swings, often referred to as "acid shock." Natural occurrences in the lake, along with rainfall, can significantly impact carbonate hardness and pH levels, potentially resulting in dangerous fluctuations. sera pond bio balance naturally and gently boosts carbonate hardness and total hardness, thereby stabilizing the pH level over time. It promotes a well-balanced mineral supply, minimizes stress, and enhances the living conditions for both fish and aquatic plants. Water Care 1. Stabilize the water 2. Improve water conditions 3.

Automatic digital pH value management for CO2 operations Processes such as adding CO2 to the water rely on the pH level and can be efficiently controlled and adjusted through it. The seramic pH Controller keeps an eye on the pH levels in your aquarium and manages a connected CO2 fertilization system based on the set parameters. To achieve this, the device to be controlled is linked to the seramic pH Controller using a socket, the desired pH ranges are established, and then the seramic pH Controller autonomously and accurately manages the adjustments. The included solenoid valve can be connected to standard CO2 systems, regulating CO2 addition according to the pH levels. This kit contains: digital seramic pH Controller with power connection and external plug solenoid valve sera pH electrode 2 suction cups and universal holder universal holder plate sera test solution pH 4.0 (with safety color indicator “red”) 100 ml (3.38 fl.oz.) sera test solution pH 7.0 (with safety color indicator “green”) 100 ml (3.38 fl.oz.) 3 m (3.3 yd.) CO2 hose 4/6 non-return valve information for use Tip: The seramic pH Controller is also ideal for operating calcium reactors and dosing pumps.

Introducing the newest generation of thermometers for aquariums and terrariums. The sera digital thermometer impresses with its vibrant liquid crystal display. It accurately measures temperatures ranging from 18 to 34 °C. Temperature indicators include: 1 brown: trend rising 2 green: current temperature 3 blue: trend falling

For easy monitoring of marine water density, you can determine the salinity (salt content) from the measured density. It's essential to maintain a consistent salinity level in your aquarium, so it's important to check the water regularly. To perform the test, fill a tall glass with the water you want to assess, then read the scale of the submerged hydrometer based on how deep it is immersed.

AQUA MEDIC PH CONTROLLER WITHOUT SENSOR The pH controller is an accurate device designed to manage the pH levels in your aquarium.

Only the pH sensor and calibration liquid are included in the delivery! EHEIM pHcontrol+e – the intelligent controller designed to monitor and adjust the pH level in your aquarium. With the EHEIM pHcontrol+e, you can effortlessly keep track of and enhance the pH in your aquarium using your smartphone, tablet, or PC/MAC through a WiFi connection and your web browser. A pH sensor detects the current pH level of the water, while the pHcontrol+e automatically manages the required CO2 supply. By regulating the magnetic valve linked to the CO2 system, it adds the necessary CO2 until the desired pH level is achieved. To utilize this feature, you will need to connect your CO2 system, such as a CO2 bottle via a pressure reducer, along with a magnetic valve (refer to the EHEIM CO2 sets) and a CO2 diffuser. The pHcontrol+e includes a day/night control and can be integrated with the EHEIM LEDcontrol+e lighting system (part of the EHEIM DIGITAL family). In addition to light, nitrogen, phosphate, trace elements, and more, aquarium plants primarily require CO2 as a crucial nutrient. The healthier they grow, the more oxygen they produce, which is necessary for the fish to breathe. Therefore, the EHEIM pHcontrol+e indirectly contributes to oxygen levels and ensures the optimal pH for your fish by adding CO2. This typically ranges between pH 6 and pH 8, with pH 7 being a neutral reference point. Note: The foundation for measuring and stabilizing the pH value is the carbonate hardness ("KH") of the water. Consequently, the EHEIM pHcontrol+e (in Smart mode) first checks the KH value, as KH, CO2, and pH levels influence one another. Features of the EHEIM pHcontrol+e: Smart controller for monitoring and regulating the pH level in the aquarium by managing CO2 addition. Includes wireless WiFi connection compatible with WLAN-enabled devices (smartphone, tablet, PC/MAC). Compatible with devices from the EHEIM DIGITAL family. Measures pH through the pH sensor (measuring range: pH 0 to pH 14). Control range of the controller is pH 6 to pH 9. Requires coupling via pressure reducer with a CO2 bottle (EHEIM CO2 set). Electronically manages CO2 addition through an interposed magnetic valve. Adjusts CO2 addition by linking with LEDcontrol+e (day/night control) in smart mode or simple/extended bio mode with its own day/night control. Pre-checks the KH value (carbonate hardness). Sets reminders for water tests and calibration. Guided calibrations for the pH sensor. Alerts for pH value deviations (up/down). Notifies when the EHEIM pH sensor needs replacement. Offers optimal performance, robust power, stable connection, and extensive memory capacity thanks to an advanced chip generation. Ensures maximum safety and reliability with a 3-year warranty.
