Seachem Prime 250ml Dechlorinator & Ammonia Detoxifier

Prime removes chlorine and chloramine, and it can be used during tank cycling to lower ammonia/nitrite levels, as it contains a binder which detoxifies these harmful elements. It is typically 5x more concentrated than standard dechlorinators, making it an ideal choice for larger tanks. It will not over-activate skimmers, and it is non-acidic so it will not affect pH. Use Prime at start-up and whenever adding or replacing water.

Directions

Use 1 capful (5 mL) for each 200 L (50 US gallons) of new water. For smaller volumes, please note each cap thread is approximately 1ml. It can be added directly to the aquarium, but it is advised to be added to new water first. If adding directly to aquarium, base the dose on full tank volume. Sulphur odour is normal. For exceptionally high chloramine concentrations, a double dose may be used safely. To detoxify nitrite in an emergency, up to 5 times normal dose may be used. If temperature is > 30 °C (86 °F) and chlorine or ammonia levels are low, use a half dose.
