Quick breathing at the water surface is an unmistakable sign for an oxygen deficiency. Unfortunately, it may then already be too late for acting appropriately.
The sera O2-Test monitors the actual oxygen level in the water within minutes and allows for acting in time. sera O2 plus provides quick oxygen supply.
Sufficient for approx. 60 measurements.
For 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.
The high quality sera vials made of glass are ideally suited for carrying out the sera water tests, but also for exact dosage of care and treatment products. The scale is very precise and meets the requirements for a high quality measurement vial.
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.
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...
The magnesium level can be increased with sera marin COMPONENT 6 magnesium. Reagent consumption depends on the calcium level of the checked water.
The salinity (salt contents) can be deduced from the measured density.
Since the salinity of marine water in an aquarium must be kept constant, the aquarium water should regularly be checked accordingly. The water to be tested is filled into a sufficiently tall water glass, and the scale of the immersed hydrometer is read off on according to its immersion depth.
