I started a new tank using AF Rock. What Aquaforest products should I use to kickstart the cycle? I had success before and want to stick with Aquaforest.

AF Rock tank startup works best when paired with a full Aquaforest approach. From day one, we recommend using: AF Bio Sand, Life Bio Fil, AF Life Source, and Bio S. These products are designed to complement each other and significantly accelerate the maturation process. Many aquarists have reported faster and more stable cycling when following this complete system.
