ThriveTabs FAQ

Everything you need to know about using ThriveTabs for targeted root-zone nutrition.

How do ThriveTabs work? +
ThriveTabs are placed beneath the substrate near the roots of aquarium plants. As the tablet breaks down, nutrients become available in the root zone where rooted plants can access them.
How deep should I place ThriveTabs? +
Push the tablet fully beneath the substrate and position it near the plant's root zone. Keeping the tablet covered helps keep the nutrients where they are intended to be used.
What plants benefit most from ThriveTabs? +
ThriveTabs are especially useful for rooted aquarium plants such as Amazon swords, Cryptocoryne, Vallisneria, Tiger Lotus and many other plants that benefit from nutrients supplied through the substrate.
Can I use ThriveTabs with an inert substrate? +
Yes. ThriveTabs can be used in inert substrates to provide concentrated nutrition directly around the roots of planted aquarium plants.
Do I still need liquid fertilizer? +
That depends on your aquarium. ThriveTabs focus on root-zone nutrition, while liquid fertilizers supply nutrients through the water column. Many planted aquariums use both approaches together, especially when the tank contains a mix of rooted plants and water-column feeders.
Can ThriveTabs be used in shrimp tanks? +
ThriveTabs are designed for freshwater planted aquariums and can be used in planted tanks that also contain shrimp when used as directed.
Will ThriveTabs cloud my aquarium water? +
ThriveTabs should be pushed fully beneath the substrate. Keeping them buried helps keep the tablet material and nutrients within the root zone rather than exposing them directly to the water column.
What's the difference between ThriveTabs and ThriveCaps? +
Both products are designed to provide nutrition directly to the root zone. ThriveTabs use a traditional tablet format, while ThriveCaps use a compact capsule format. They offer two different ways to place root-zone nutrition beneath the substrate.
Which size of ThriveTabs should I choose? +
ThriveTabs are available in 30-count and 75-count sizes. The smaller jar is a convenient option for smaller planted aquariums or first-time users, while the larger jar provides more tablets for established tanks or ongoing use.
