Stability and Reliability It provides a buffer and maintains the pH level. It counteracts biogenic scaling and creates optimal conditions for specific species (for instance, African Cichlids). Carbonate hardness (KH) is among the less critical parameters of aquarium water. Most fish in freshwater aquariums thrive in relatively harder water. Furthermore, KH serves as a buffer that helps to prevent dangerous fluctuations in pH levels (including a sudden rise in acidity). For community aquariums, it is advisable to maintain a minimum KH of 6°dkH (even higher for special cases like African Cichlids). This ensures the health of the fish and keeps the aquarium water resilient and easy to care for. Sera KH/pH-plus will accurately and sustainably elevate KH to the desired level. The pH will increase gradually and, more importantly, will be securely stabilized.

It effectively breaks down ammonium and nitrite, utilizing specialized cleaning bacteria. Sera marin bio reefclear, a product of Sera bio technology designed for marine aquariums, works to eliminate ammonium and nitrite with the aid of these beneficial bacteria.

A proper magnesium concentration is essential for the health of marine invertebrates and algae. A prime example is the red calcareous algae, which require substantial amounts of magnesium to form their skeletons. Natural seawater typically has around 1300 mg/l of magnesium. To create optimal conditions in your marine aquarium, it's crucial to maintain this concentration. The Sera magnesium test allows you to quickly and easily assess the magnesium level in your aquarium. You can also effectively boost magnesium levels using Sera magnesium plus. Additionally, magnesium levels can be raised with Sera marin COMPONENT 6 magnesium. The amount of reagent needed will depend on the calcium levels in the water you are testing. Store in a cool, dark place! Instructions for Use: In a marine water aquarium, maintaining an optimal magnesium level is vital for the thriving of invertebrates and decorative algae. Red calcareous algae are a great example, as they require high magnesium levels for their skeletal structure. Natural marine water contains around 1,300 mg/l, which should also be replicated in your aquarium for ideal conditions. The Sera magnesium-Test enables you to monitor your aquarium’s magnesium levels swiftly and efficiently. If you have prior testing experience with the Sera calcium-Test, this will be even easier for you. You can easily enhance the magnesium level in your marine water aquarium by using Sera marin COMPONENT 6 magnesium. Directions for use: Shake the reagent bottles well before use! Avoid letting the tested water come into contact with aquarium or pond water! Rinse the measurement vial several times with the water you wish to test, then empty it. Dry the outside of the vial. Rinse the syringe multiple times with the water to be tested, then use it to fill the vial with 2 ml of this water. Add 6 drops of reagent 1 and shake the vial until the liquid is evenly mixed. Any cloudiness that appears will not affect the test. Add one level measuring spoon (provided in the kit) of reagent 2 to the vial and gently swirl (do not shake) until the powder has dissolved. Gradually add reagent 3 drop by drop while counting them. After every 5 drops, release pressure on the bottle to allow air to enter. Shake the vial after each drop until the color shifts from pink to blue (not violet) and remains stable for at least 30 seconds while you gently whirl the vial occasionally. Note the number of drops used. Empty and thoroughly rinse the measurement vial with tap water, then rinse it several times with the water to be tested and empty it again. Dry the outside of the vial. Use the syringe to take up 2 ml of the water to be tested and fill the vial. Add 6 drops of reagent 4 and shake the vial until the liquid is evenly mixed. Any cloudiness that appears will not affect the test. Add one level measuring spoon (included in the kit) of reagent 5 to the vial and gently swirl (do not shake) until the powder has dissolved. Add reagent 3 drop by drop while counting the drops, releasing pressure on the bottle after every 5 drops to allow air to be drawn in. Shake the vial after each drop until the color changes from red to green and remains stable for at least 30 seconds while whirling the vial occasionally. Note – you will require significantly more drops for this measurement compared to the first measurement! To find the magnesium level, subtract the number of drops used for the first measurement from the number of drops used for the second measurement. Multiply the remaining number of drops by 60 to calculate the magnesium level in mg/l. For example, if the first measurement used 4 drops and the second used 24 drops, subtracting gives you 20 drops. Multiplying 20 drops by 60 results in a magnesium level of 1,200 mg/l. Cleaning: Thoroughly clean the vial and syringe with tap water before and after each test. Close the reagent bottles immediately after use and do not switch caps. Store at room temperature and away from light. This product is intended for testing ornamental fish aquariums and pond water only. Store in a cool, dark place!
