Tropic Marin ATM29432 Bio Calcium Supplement 1500g / 3 lbs 5oz

Biological ideal magnesium supplement for reef aquariums A sufficient supply of Magnesium is as assential for the growth and wellbeing of reef building coralline algae as Calcium. It is one of the major constituents of seawater and is directly involved in algae photosynthesis, i.e. the conversion of carbon dioxide (CO2) and light into organic compounds. The addition of plain magnesium salt, however, is not sufficient and interferes with the ionic balance of the tank water. Tropic Marin BIO-MAGNESIUM creates a natural envireonment in the aquarium and delivers Magnesium and carbon dioxide in a natural, biological available ionically balanced form. How to use: The natural concentration of Magnesium is 1280-1300 ppm. Calculate the total system water volume and begin by measurin the magnesium concentration of your aquarium water. One level measuring spoon increases the magnesium level of 30 US-gallons / 110 I of tank water by about 10ppm. Therecommended maximum water per day! Sprinkle one measuring spoon full of Tropic Marin BIO-MAGNESIUM onto the surface of the water, where it is being circulated by tour pump. Take care not to allow a larger amount of undissolved BIO- MAGNESIUM to come into contact with invertebrates. Wait for each spoonful to dissolve completely before adding the next. Check the aquarium waters specific gravity on a regular basis as this may gradually increase over time with the addition of Tropic
