## Summary description

sera Phosvec Granulat is a 500 g subsoil fertiliser designed for planted aquariums. Supplied as granules, it provides nutrients directly to plant roots to support healthy growth and prevent deficiencies. Intended for use during substrate preparation or maintenance, it benefits aquatic plants by improving root nutrition and overall vitality.

## Long description

sera Phosvec Granulat 500 g is a granular subsoil fertiliser formulated for use in planted aquariums. The product is designed to supply essential nutrients directly to plant roots when applied during substrate preparation or maintenance. Supplied in a 500 g pack, the granules integrate into the substrate to support root development and help prevent nutrient deficiencies that can limit plant growth and vitality.
Advantages
The granular form allows targeted delivery of nutrients to the root zone where aquatic plants absorb them most efficiently. Applying the product when setting up the substrate or during substrate maintenance ensures prolonged nutrient availability without clouding the water column. As a subsoil fertiliser, it complements water column dosing by focusing on root nutrition, which can improve overall plant health and reduce signs of deficiency.
Suitable for
 Freshwater planted aquariums with rooted aquatic plants
 Substrate preparation during new tank setup
 Maintenance of established planted tanks to replenish root nutrients
 Hardscape aquascapes where root-feeding plants are used
When it may not be suitable
sera Phosvec Granulat is intended for use in planted freshwater aquaria and is not designed for direct dosing into the water column as a complete fertiliser. It may not be necessary in tanks that rely exclusively on water-column fertilisation or in systems with substrate-free setups such as bare-bottom tanks. Use with caution in sensitive biotope recreations where additional nutrients could alter water chemistry.
Key specifications
 Form: granular subsoil fertiliser
 Net weight: 500 g
 Intended application: placed into substrate to supply root-zone nutrients
 Primary function: prevent nutrient deficiencies and support root development
 Suitable water type: freshwater aquaria with planted substrate
How to use
Place the granules into the substrate during aquarium setup by distributing them in planting holes around the roots of individual plants, or incorporate them into the top layer of the substrate where appropriate. When used for maintenance, insert small amounts near established plant roots using a planting tool or similar implement. Follow any dosing guidance provided on the product label regarding the quantity per plant or per volume of substrate; avoid dispersing large amounts into the open water to prevent clouding.
What to consider before purchase
 Compatibility with your planted aquarium type (freshwater only)
 Whether you need root-zone supplementation in addition to water-column fertilisers
 Tank setup: substrate depth and type must allow placement of granules near roots
 Presence of sensitive plants or biotope requirements that limit additive use
Usage recommendations
For best results, use sera Phosvec Granulat during substrate planting and repeat localised applications during long-term maintenance as plants show signs of deficiency. Combine with appropriate water-column fertilisation and regular monitoring of plant health and water parameters to maintain balanced growth.
