Dennerle Plants Power Caps

Dennerle Plants Power Caps are substrate fertilizer capsules providing an ideal blend of essential macro nutrients (nitrate, phosphate, potassium) and micro nutrients (iron, trace elements) directly at the root zone. Designed to be inserted deep into the substrate at the base of the plant, they encourage root growth, health and long-term vitality.

Perfect for strongly rooting species such as Echinodorus, Cryptocorynes and other stem plants, Power Caps replenish depleted nutrients in the substrate over time — either as a supplement to liquid fertilization or as a targeted first aid for nutrient deficiency symptoms.

The capsule shell dissolves naturally in the substrate, while the slow-release beads remain and continue delivering nutrients gradually. The beads are completely harmless to both plants and animals.

• Start supplementing 2–3 months after aquarium setup to prevent nutrient deficiencies
• Can also be used at initial setup to enrich the substrate from day one

FAQ

Do the beads dissolve in the substrate?
No — only the capsule shell dissolves. The slow-release beads remain in the substrate and are completely harmless to plants and animals.

When should I start using Power Caps?
You can use them at setup for an enriched substrate from the start, or begin supplementing 2–3 months into the aquarium’s life to prevent deficiencies.

Are they safe for shrimp?
Yes — fully safe for all aquarium inhabitants including shrimp, fish and snails.
