Water testing for experienced pond keepers Experienced pond keepers check their pond water regularly. This allows taking measures, for instance against algae, quickly and easily, without the need to use chemicals. The sera Koi aqua-test box contains the following test kits: pH value total hardness (GH) carbonate hardness (KH) ammonium/ammonia (NH4/NH3) nitrite (NO2) nitrate (NO3) phosphate (PO4) iron (Fe) and copper (Cu)  

Quick and easy monitoring Routine monitoring or safety check: The sera Quick Test provides the optimal possibility to check the most important water parameters (pH value, carbonate hardness, total hardness, nitrate, nitrite and chlorine) in the aquarium with just one test strip quickly and without any problems. Immerse a test strip in your tank for a second, then wait for 1 minute and compare the intensity of its colors to the chart on the package. A safe procedure that also supports beginners achieve best possible water quality in their aquariums. In case the measurement reveals deviations from the optimal levels, the sera liquid tests allow determining the differences exactly.

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.

Makes it easy to monitor the pH value in fresh and marine water and ponds. For approx. 100 measurements In case of too low pH values we recommend sera KH/pH-plus (in freshwater aquariums) or sera pond bio balance (in ponds), in case of too high values in freshwater aquariums we recommend sera pH/KH-minus or filtering through sera super peat.

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

sera gH-Test FRESH WATER , PONDWATER TESTINGCAREMakes it easy to monitor the total hardnessFor approx. 420°dGH. In case of too low GH values we recommend sera mineral salt. High total hardness levels can be lowered by mixing in R/O water. For creating soft water we recommend adding sera blackwater aquatan or filtering through sera super peat. Directions for use: Shake reagent bottle well before using! Do not allow tested water to contact aquarium or pond water!  1. Rinse the measurement vial several times with the water to be tested, then fill to the 5 ml mark. Dry the vial on the outside. 2. Add reagent drop by drop. Shake vial gently after every drop, until the color changes from red via brown to green. 3. The number of drops used from the reagent represents the existing total hardness (in °dGH). E.g., 5 drops = 5°dGH. 4. Cleaning: Clean the vial thoroughly with tap water before and after each test. Close reagent bottle immediately after use. Store at room temperature and away from light. Keep locked up and out of the reach of children. For testing ornamental fish aquariums and pond water only.  US Information for use Most ornamental fish originate from countries where the soil is poor in minerals. However, it is exactly the opposite in many other areas around the world. Rain water dissolves calcium and magnesium from the soil and consequently creates hard water. With the sera gH-Test, you can quickly determine the exact total hardness. Looking at the natural conditions helps selecting the optimal fish stock for a community aquarium, and is a precondition for successful breeding. High total hardness levels can be lowered by mixing in R/O water. A combination of sera aquatan and sera blackwater aquatan or filtering through sera super peat will create soft water, as required for most South American fish (e.g. from the Amazon basin).

Automatic digital pH value control for CO2 operation Operations like CO2 addition to the water depend on the pH value and, correspondingly, can easily be controlled and regulated via the pH value. The seramic pH Controller monitors the pH value of the aquarium water and controls a connected CO2 fertilization system according to the adjusted parameters. To do so, the unit to be controlled is connected to the seramic pH Controller by means of a socket, the desired pH ranges are set and then independently and reliably controlled and regulated by the seramic pH Controller. The solenoid valve included in the kit can be connected to common CO2 systems and regulates CO2 addition depending on the pH value. The kit consists of: 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.)
