FAQ: How often can I dose Seachem Prime®?

Prime® will bind ammonia into a non toxic form for 48 hours and allows for the removal via your tank's bio-filter (beneficial bacteria). If ammonia still persists after 48 hours, you can re-dose every 48 hours as necessary until ammonia levels reach 0 ppm.

 If you are not detoxifying ammonia, but are instead carrying out very frequent water changes (more frequent than every 48 hours) and are dosing Prime® for the purpose of preparing new water for the tank, we recommend to treat all new water with an appropriate dose of Prime® (5 mL per 50 gallons of water) before it is added into the system.  This will prevent unnecessary overdoses in the main system.
