100 ml pH 4.01 Calibration Solution.

A small amount of chlorine in the aquarium water is not harmful, but higher concentrations can quickly lead to the death of shrimps, crayfish and fish. Good for +- 45 tests.

The sera O2-Test monitors the actual oxygen level in the water within minutes and allows for acting in time up on oxygen deficiency.

In order to achieve an optimal situation in an aquarium, it is extremely important to regularly test the water quality. The Easy-Life 6 in 1 Test Strips are quick to use and extremely accurate.

Both fish waste and feeding are possible causes for phosphate introduction into the water. A part is taken up as a nutrient by plants, an excess, however, provides nutrition for unwanted algae.

The updated Combo Pen P160 Pro has been developed further and now features improved software. The major advantage of this model is its analogue EC calibration. This means that the calibration solution does not need to have a temperature of exactly 25 C.
