Dr. Tim’s One & Only – Live Nitrifying Bacteria (Saltwater) – 2 oz

Kick‑start your biofilter and avoid New Tank Syndrome. One & Only adds live nitrifying bacteria that instantly convert toxic ammonia and nitrite—safe for reefs, nanos, and seahorse systems. 100% natural and odor‑free. 🐠

🧪 How to Use

Shake well. Dose 10 mL per 10 gallons (38 L). For best results, use the entire bottle at one time matched to your system volume. Turn off UV, ozone, and protein skimmer, and remove filter socks for 48 hours after dosing so bacteria can settle on surfaces. Do not freeze. Can’t be overdosed.
