What substrate is best for a planted tank?

Aquasoil is the best all-around choice for most planted tanks. It provides nutrients, lowers pH slightly, and supports root growth. For a budget option, use an inert gravel base with root tabs placed near heavy root feeders like Cryptocoryne and Amazon swords.

Do I need CO2 for a planted tank?

No, many beautiful planted tanks run without CO2. Low-tech setups using aquasoil, moderate lighting, and easy plants like Anubias, Java fern, and Cryptocoryne can thrive. CO2 becomes necessary if you want fast-growing stem plants or carpet plants like Monte Carlo.

What are root tabs and are they safe for shrimp?

Root tabs are slow-release fertilizer capsules you bury in the substrate. They provide nutrients directly to plant roots. Most root tabs are safe for shrimp if used as directed. Avoid pushing them too close to the surface where shrimp might ingest them.

Quick Answer

A successful planted tank starts with the right substrate, adequate lighting, and consistent nutrients. Low-tech setups using aquasoil and root tabs can thrive without CO2; high-tech setups with injection systems enable demanding plants like Monte Carlo and Rotala.
