Description

MasterLine I is a concentrated micronutrient combination fertiliser for aquatic plants. It contains strongly chelated iron, manganese, zinc, boron, copper and molybdenum. It is recommended to use MasterLine I together with MasterLine II and MasterLine Carbo. In this way the aquatic plants have all the nutrients necessary for healthy growth. Thanks to the high-quality chelators, the nutrients in MasterLine I retain their properties over a longer period of time, keeping the water crystal clear and offering the possibility of a weekly dosage. This gives the aquarist the freedom to choose between the two dosages.

  • Fertiliser for aquarium ornamental plants with all essential micronutrients
  • Contains iron, manganese, zinc, boron, copper, and molybdenum
  • Compatible with all types of aquatic life, including shrimp
  • Suitable for daily or weekly dosing

Does it make sense to already add half the dose every 2nd day during the cycling phase?

In a planted aquarium it always makes sense to supply the plants with nutrients from the very beginning. You can find everything important on the topic of fertilizing during the cycling phase in our wiki: https://www.aquasabi.business/aquascaping-wiki_naehrstoffe_duengung-in-der-einfahrphase

Ganz erstaunlich!

Ich hatte früher die Easy Life Serie im Gebrauch und war durchaus zufrieden. Ich dünge zusätzlich mit CO2, habe als Beleuchtung die daytime Matrix-Serie und hatte auch ein paar Wochen den Nano+ von Twinstar im Einsatz. Nachdem ich plötzlich mit Blaualgen und sterbenden Pflanzen Probleme bekam, habe ich mein Düngekonzept neu aufgesetzt und bin auf die MasterLine-Produkte umgestiegen und habe gleichzeitig den Nano+ wieder abgebaut. Sehr schnell konnte ich danach eine deutlich gesteigerte Vitalität meiner Aquarienpflanzen (darunter auch durchaus empfindliche Schätzchen) bemerken und bin bis heute überrascht, wie stabil sich diese positive Entwicklung hält.

Selbst meine empfindlichen Cryptocorynen-Wiesen haben sich komplett erholt und strotzen inzwischen nur so vor Gesundheit, so dass ich regelmäßig büschelweise an befreundete Aquarianer abgeben kann.

Ich bin sehr zufrieden mit diesen Produkten und werde sie weiterhin verwenden.
