NilocG Thrive Caps are new and improved aquarium plant root tabs designed to deliver concentrated nutrients directly to the root zone of planted freshwater aquariums. They are similar to the previous ThriveTabs, but use a cleaner, more concentrated capsule format that requires no additives to hold the fertilizer together.

Because the capsules are smaller and more concentrated, they still deliver strong nutrient support while reducing unnecessary filler. The updated formula also helps reduce the clouding that some aquariums experienced with the older ThriveTabs, making them a cleaner choice for planted tank substrates.

Each capsule contains a nutrient-rich blend of dry Thrive fertilizer mix, iron-rich clay, and mineralized topsoil to support healthy root development, stronger growth, and long-term plant nutrition. They are especially useful for heavy root-feeding aquarium plants such as swords, crypts, vallisneria, lotus, and other rooted freshwater plants.
