MasterLine All In One Red is a specialised fertiliser that does not contain nitrate and is specifically designed to promote the strongest pigmentation in red plants in aquariums. This formula contains all the necessary micro and macro nutrients to optimally nourish plants while supporting a slow growth rate. This makes it particularly suitable for aquariums with a high fish stock.

This fertiliser is ideal for aquariums that benefit from nitrate in the substrate and nitrate excreted by aquarium inhabitants. It is particularly recommended for use in aquariums with nutrient-rich substrates such as Aquasoil or soils enriched with MasterLine Root Caps. MasterLine All In One Red can be administered daily or weekly, depending on the needs of the aquarium.

MasterLine All In One Red is compatible with all aquatic life, including shrimp, and should not be combined with UV lamps. After a water change of more than 50%, a triple dose of the fertiliser is necessary. For maximum efficiency, it is recommended to use it in conjunction with MasterLine Carbo.

This dosage rate has been tested to work well for most tanks. However, if you have a very sparsely planted tank or a very densely planted tank, it is recommended to adjust the dosage based on observations of plant growth.
