pH and aquariumspH and aquariumsWhy is pH so important in your aquarium? It determines the health of fish, plants and water quality. Learn how to measure, calibrate and maintain pH accurately and discover which fish need which pH value. A stable pH is more important than an exact value.Calibrating a swimming pool pH probe: a complete guideCalibrating a swimming pool pH probe: a complete guideA correctly calibrated pH probe is crucial for clear pool water and optimal operation of your dosing system. This comprehensive guide covers the operation, cleaning, calibration and storage of pH probes. You will also find a complete overview of the most popular European pH control systems – from BWT and Hayward to Sugar Valley and Kripsol – with their required pH values.ORP probe for swimming pools: everything you need to knowORP probe for swimming pools: everything you need to knowA clear and safe swimming pool starts with effective disinfection. In this blog we explain what ORP (oxidation-reduction potential) is, why this value is essential for pool water and how to measure ORP with an ORP probe. We discuss the difference between liquid chlorine and salt electrolysis, the choice between platinum and gold ORP probes, and how to calibrate the ORP probe with ORP buffer solutions.Pool salt tester: measuring salt contentPool salt tester: measuring salt contentA saltwater pool with salt electrolysis produces chlorine on site from a small amount of salt. The right salt content is crucial: too little results in insufficient disinfection, too much can damage the electrolysis cell. So measure regularly with a digital salt tester and top up with pure pool salt. Meytec offers the GT-500S salt tester for swimming pools. That way you keep your system running optimally for clear and soft pool water.Maintaining pH and ORP probes: how to keep your measurements reliableMaintaining pH and ORP probes: how to keep your measurements reliablepH and ORP probes are indispensable for a healthy swimming pool or aquarium. Without maintenance, they lose their precision due to deposits, dirt and drying out. Clean them regularly, store them moist in KCl solution and calibrate them with fresh buffer solution. That way your measurements stay reliable and your probes last longer. Meytec offers all the solutions and accessories you need for optimal maintenance.
