Aquarium plant fertilizer tablets sera Florenette 24 tablets dosing 1 tab/20 L

sera Florenette are pressed fertilizer tablets designed for aquarium plants that absorb nutrients mainly through their roots. Supplied as a pack of 24 tablets, each tablet acts as a nutrient depot when placed in the substrate near plants, delivering essential minerals and trace elements to support healthy, colorful growth without adding nitrate or phosphate. The formulation includes iron in a readily available form and natural growth enhancers to support robust early development and ongoing vitality. The product is made in Germany and is compatible with invertebrates and common freshwater aquarium conditions. Recommended dosing is one tablet per 20 liters every other week.

Advantages

Tablets provide a long-lasting depot effect directly at the root zone, ensuring an even and sustained supply of minerals and trace elements. The formulation avoids nitrate and phosphate while supplying iron and natural growth promoters to ease the start-up phase and promote steady plant growth. Because nutrients are supplied to roots, the product is well tolerated by invertebrates and helps reduce algal outbreaks by supporting healthy plant competition.

Suitable for

• Freshwater aquaria with substrate-planted aquatics
• Plants that take up nutrients mainly via roots
• Community tanks containing invertebrates (shrimp, snails)
• Aquaria where a nitrate- and phosphate-free root fertilizer is preferred

When it may not be suitable

sera Florenette is not intended as a comprehensive water-column fertilizer and therefore may not fully meet the needs of fast-growing stem plants that rely mainly on foliar nutrient uptake. In aquaria that already have very high nutrient levels in the substrate or frequent liquid dosing, additional root tablets could lead to excessive local concentrations and are not necessary.

Key specifications

• Form: pressed root fertilizer tablets
• Pack size: 24 tablets
• Dosing: 1 tablet per 20 litres, every other week
• Contains essential minerals, trace elements and available iron
• Free from nitrate and phosphate
• Intended use: freshwater aquarium plants
• Country of manufacture: Germany

How to use

Place a tablet directly into the substrate close to the plant roots or in holes made beside clusters of plants. For best results dose one tablet per 20 litres of aquarium water every two weeks. Reposition tablets as plants expand or after substrate rearrangement. Do not crush tablets; allow them to dissolve slowly to maintain the depot effect at the root zone.

What to consider before purchase

• Intended primarily as a root fertilizer — assess whether your plants rely on root or foliar nutrient uptake
• Check aquarium volume to calculate required number of tablets and dosing intervals
• Not a substitute for complete water-column fertilization if fast-growing plants dominate the tank
• Compatible with tanks containing invertebrates, but monitor overall nutrient balance

Usage recommendations

For typical maintenance dose one tablet per 20 L every other week and place tablets directly next to plant root systems; combine with an appropriate water-column fertilizer if your plant selection requires additional macronutrients.
