Aquarium Root Tabs for Swords, Crypts and Substrate-Planted Stem Plants in Gravel, Sand or Planted Tanks

Give root-feeding aquarium plants the nutrients they need where they grow. These fertilizer tablets sit beneath the substrate near each plant’s base, supporting strong, healthy growth and a more vibrant underwater setting for your fish.

They suit planted swords, crypts and stem plants, making them a practical addition to routine care in aquariums using gravel, sand or planted-tank substrate. Choose from 10, 25 or 50 tabs to match your planting plan.

Key Features

• Place each tablet 1–2 inches into the substrate near the plant base, bringing nourishment to the root zone where rooted aquarium plants can use it.
• Space tabs 3–6 inches apart according to plant size and density, giving each planted area an appropriate place in your feeding routine.
• Replace the tablets every 1–2 months, or as needed, for a straightforward schedule that supports healthy plant growth over time.
• Use fingers or tweezers during placement to reduce disturbance around nearby roots and keep established plants settled.
• Pair the tablets with liquid fertilizer when your aquarium care routine calls for a more complete nutrient solution.
• Made for root-feeding plants rather than floating plants or mosses, so you can choose fertilizer according to how your aquarium plants feed.
