Tips
Dose daily for the first week, then weekly or at water changes. Test ammonia and nitrite regularly and add fish slowly.
Questions owners ask
Can I add fish immediately?
Add fish slowly and keep testing water. Bacteria help, but cycling still takes time.
Can I overdose?
Seachem says overdosing is not harmful, but follow label directions.
