Compare the Home Brew Blends

Each formula offers a different strain combination. Rotating blends can diversify your feeding routine; results vary with livestock, water quality, lighting, and flow.

Dosing & Feeding

Shake before use. The published starting recommendation is 5 mL per 15 gallons of aquarium water, three times per week. Follow the directions on your bottle if they differ. Monitor nutrients and livestock response when adjusting feeding amounts. At the recommended rate, a 15 oz bottle is approximately a one-month supply for a 75-gallon aquarium.

Storage & Handling

• Shelf stable before opening.
• After opening, refrigerate at 32–39°F (0–4°C).
