The primary function is to deliver a complex of minerals and organic biostimulators directly at the root zone — where rooted plants absorb the majority of their nutrients, and where liquid column fertilisers cannot reach effectively. The secondary function is to actively maintain and restore the ion exchange properties of the substrate, preserving its fertility over extended periods.\u003c\/p\u003e\n\u003cp\u003eThe 15-capsule format is the ideal starting point for nano and small planted aquariums, or for aquascapers trying substrate capsule fertilisation for the first time before committing to the larger 80-capsule pack.\u003c\/p\u003e\n\u003ch4\u003eFormula Highlights\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDelivers nutrients directly to the root zone for maximum uptake efficiency\u003c\/li\u003e\n\u003cli\u003eMaintains and restores substrate ion exchange capacity\u003c\/li\u003e\n\u003cli\u003eContains a complex of minerals and organic biostimulators\u003c\/li\u003e\n\u003cli\u003eSupports stable plant arrangements over extended periods\u003c\/li\u003e\n\u003cli\u003e15 capsules — ideal for nano and small planted aquariums\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eDosing Instructions\u003c\/h4\u003e\n\u003cp\u003eApply capsules using tweezers or an applicator, placing them every \u003cstrong\u003e10–15cm near plant roots\u003c\/strong\u003e at a minimum depth of \u003cstrong\u003e4cm\u003c\/strong\u003e.

Capsules are placed deep in the substrate (minimum 4cm) and release nutrients slowly at the root zone. When used as directed, they do not significantly affect water column chemistry and are safe for Neocaridina and Caridina shrimp.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow many capsules do I need for my tank?\u003c\/strong\u003e\u003cbr\u003ePlace one capsule every 10–15cm near plant roots. For a typical 30-litre nano tank with moderate planting, 15 capsules will cover the initial application with some remaining for the next cycle.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow often do I reapply?\u003c\/strong\u003e\u003cbr\u003eEvery 3–4 weeks.
