Sera phosphate-Test (PO4)
Makes it easy to monitor the phosphate level in fresh and marine water
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 sera PO4-Test quickly and easily provides an overview of current phosphate levels. Excess phosphate is easy to remove with sera phosvec･clear (freshwater) or sera phosvec Granulat (fresh and marine water) or sera pond phosvec (pond). Sufficient for approx. 60 measurements. VOLUME: 15ml
Sera ammonium test
Makes it easy to monitor the ammonium/ammonia level in fresh and marine water.
Ammonium and ammonia mainly arise from fish waste. They are converted into each other depending on the pH value. While ammonium is mostly harmless, ammonia is toxic to fish.
The sera NH4/NH3-Test allows monitoring the total concentration of both (the actual ammonia level can be calculated according to the pH value the using the included chart).
In case of acute danger, sera toxivec (freshwater) or sera pond toxivec (pond) provide help. sera bio nitrivec (freshwater), sera marin bio reefclear (marine water) or sera pond bio nitrivec (pond) actively counteract lasting enrichment of these substances.
Sufficient for approx. 60 measurements.
