Seachem Flourish Tabs 10 Pack – Aquarium Plant Root Fertilizer

Seachem Flourish Tabs are nutrient-rich root fertilizer tablets designed to support healthy growth in freshwater aquarium plants. The tablets are placed directly into the substrate, where nutrients become available near the plant roots.

This package contains 10 tablets and is especially useful for rooted aquarium plants such as Amazon swords, Cryptocoryne, Vallisneria, tiger lotus, and other plants that absorb a significant portion of their nutrients through the substrate.

Key Features

• Root-Zone Fertilization: Places nutrients directly into the aquarium substrate near plant roots
• Supports Plant Growth: Helps maintain healthy roots, leaves, stems, and overall plant development
• Slow-Release Tablets: Gradually supply nutrients within the substrate between applications
• Trace Elements: Provides important elements that may become depleted in planted aquariums
• Convenient 10 Pack: Suitable for targeted fertilization or smaller planted aquarium layouts
• Freshwater Aquarium Use: Designed for planted freshwater aquariums

How to Use

Insert one Seachem Flourish Tab deeply into the substrate for every 4–6-inch radius of planted area. Distribute the tablets evenly throughout the aquarium or concentrate them near plants with established root systems.

Push each tablet completely beneath the substrate to keep nutrients near the root zone and reduce unnecessary release into the water column. Replace the tablets as needed, generally every three to four months.

A standard 10-gallon aquarium may require approximately six tablets when dosed according to Seachem’s recommended spacing. Actual usage depends on the aquarium footprint, plant placement, substrate depth, and number of rooted plants.

Plant Fertilization Tips

• Place each tablet deep beneath the substrate near the plant roots
• Space tablets according to the planted area rather than aquarium volume alone
• Avoid crushing or dissolving the tablets directly into the water
• Use aquarium tweezers for precise placement when necessary
• Reposition tablets as plants spread or the aquascape changes
• Monitor plants for yellowing, stunted growth, pinholes, or other signs of nutrient deficiency
• Maintain suitable lighting, carbon availability, and stable water conditions
• Remove damaged or decaying leaves during routine aquarium maintenance

Using Flourish Tabs with Liquid Fertilizer

Flourish Tabs may be used as part of a broader planted-aquarium fertilization routine. Root tabs primarily place nutrients within the substrate, while liquid fertilizers supply nutrients through the water column.

Plants differ in how they absorb nutrients. Heavy root feeders may benefit significantly from substrate fertilization, while stem plants, floating plants, mosses, and plants attached to hardscape may rely more heavily on nutrients available in the water.

Follow the directions for every fertilizer being used and adjust dosing according to plant growth, aquarium conditions, water testing, and signs of nutrient deficiency.

Important Planted Aquarium Note

Fertilizer alone cannot correct inadequate lighting, unstable carbon dioxide, poor water quality, damaged roots, unsuitable substrate conditions, or improper plant placement. Healthy aquarium plant growth requires an appropriate balance of nutrients, light, carbon, and routine maintenance.

Do not place Flourish Tabs where fish may dig them up or where the tablets will remain exposed. If a tablet becomes uncovered, push it back beneath the substrate.

Frequently Asked Questions

What are Seachem Flourish Tabs used for?
Flourish Tabs are root fertilizer tablets used to supply nutrients within the substrate of freshwater planted aquariums.

How often should Flourish Tabs be replaced?
Seachem recommends replacing the tablets as needed, generally approximately every three to four months.

How many Flourish Tabs should I use?
Insert one tablet for every 4–6-inch radius of planted substrate. The number required depends more on aquarium footprint and plant placement than total water volume.

How many gallons does the 10-pack treat?
There is no exact gallon rating because dosage is based on substrate area. Seachem states that a standard 10-gallon aquarium may require approximately six tablets.

Which plants benefit most from Flourish Tabs?
Root-feeding plants such as Amazon swords, Cryptocoryne, Vallisneria, tiger lotus, and Aponogeton commonly benefit from substrate fertilizer tablets.

Can Flourish Tabs be used with sand?
Yes. Insert the tablets deeply enough beneath the sand to keep them near plant roots and prevent them from becoming exposed.

Can Flourish Tabs be used with gravel?
Yes. Push each tablet deeply into the gravel near the root zone of the plants being fertilized.

Can I use Flourish Tabs with liquid aquarium fertilizers?
Yes. Root tabs and liquid fertilizers may complement each other because different aquarium plants absorb nutrients through their roots and leaves in different proportions.

Do Flourish Tabs replace aquarium lighting or carbon dioxide?
No. Plant health also depends on suitable lighting, carbon availability, stable water conditions, and appropriate aquarium maintenance.

Should Flourish Tabs be placed directly in the water?
No. They should be pushed completely beneath the aquarium substrate near the plant roots.
