INVITAL Ferox 250 ml

Unlike conventional aquariums, heavily lit and overgrown aquariums also require the macronutrients nitrogen, phosphorus and potassium. Adding them to regular aquariums would be counterproductive. For this reason, there is INVITAL Macro, which is ideal in combination with Ferox. Unlike other fertiliser brands, you save money because you do not need to buy 3 additional fertilisers in the form of a nitrogen, phosphorus and potassium fertiliser, but receive one with the right ratio of each nutrient. The form of iron used is suitable both for aquariums with low pH where CO2 is added and, unlike many other iron fertilizers, also for aquariums with high pH. Thanks to the iron chelate DTPA, the iron can also be taken up by the plants in the aquarium without adding CO2 with a higher and neutral pH. At the recommended dosage per week, you can supply up to 0.25 mg/l of iron per 100 litres. So with Ferox you can fertilize even heavily overgrown aquariums at the recommended doses and the plants will still have enough iron. Most fertilisers on the market deliver 2 to 3 times less iron at the recommended rate compared to Ferox.
