Aquarium Plant Root Tabs 20-Pack

Aquarium Plant Root Tabs are pressed nutrient tablets designed to be inserted directly into the substrate beneath root-feeding plants such as Amazon swords, Vallisneria, and Cryptocoryne species. Each tablet provides a slow-release blend of nitrogen, phosphorus, potassium, and iron that sustains plant roots for up to three months. This targeted delivery method ensures nutrients reach plant roots efficiently without elevating free nutrient levels in the water column, minimizing algae risk. Simply push one tablet into the substrate 5-8cm from the plant's base every 8-12 weeks. A pack of 20 tablets is sufficient for most small to medium planted aquariums.
