Aqua Algae 8oz Concentrated Guillard's F2 Formula

GROW YOUR OWN "POD" FOOD: Stop overpaying for small, short-lived bottles of phytoplankton. Our concentrated F/2 formula is the secret to easily growing your own endless, nutrient-dense supply of live microalgae to feed your copepods, rotifers, and corals. ULTRA-CONCENTRATED 8oz BOTTLE: A little goes a long way. This 8oz (236mL) bottle is enough to make over 230 liters (60+ gallons) of full-strength culture medium. It's the most economical way to support a thriving reef ecosystem. THE PROFESSIONAL STANDARD (GUIL-LARD'S F/2): Don't guess with your fertilizer. Our solution is based on the scientifically proven Guillard's F/2 formula, containing all essential macronutrients, trace minerals, and vitamins (B1, B12, Biotin) for explosive algae growth. SILICATE-FREE & REEF SAFE: Brewed with pure, lab-grade ingredients. This formula is 100% silicate-free, so it won't trigger a diatom (brown algae) bloom in your display tank. It's completely safe for all reef inhabitants when used as directed. EASY TO USE FOR BEGINNERS: Includes clear, simple instructions. Just add 1mL per 1 Liter (or 2mL to a standard 2L pop bottle) of new saltwater, add your starter culture, and provide light. Shake well before each use.
