pH controller (without probe) pH monitor and controller The pH controller is a precision instrument for controlling the pH value in aquaria. In combination with a CO2 system and a solenoid valve the pH can be maintained at a constant level, and the CO2 supply to aquatic plants or into a Calciumreactor can be controlled. The unit is supplied with a large LED...

Oxygen test Salifert (O2) Oxygen is highly essential for all life forms. Especially corals and marine fish require oxygen concentrations at saturation level. This is because of the low solubility of oxygen in saline water which is approx. 5 - 7 ppm. The oxygen test measures oxygen concentration in just a few minutes. Approx. 50 tests per kit....
