Seachem Prime

Seachem Prime is a complete, concentrated conditioner for freshwater and saltwater. It removes Chlorine and Chloramine. It detoxifies ammonia, nitrite and nitrate. Five times more concentrated than competing products.

Almost all aquarium brands produce a product that removes chlorine. However, none of these can match the quality, concentration or effectiveness of Seachem's flagship product: Prime. Prime does not affect pH. For seawater, it has the added bonus of not over-activating the skimmers.

Seachem Prime can be used while turning the aquarium in to reduce ammonia and nitrite. It contains a binder that detoxifies ammonia, nitrite and nitrate, allowing the biofilter to remove it more efficiently. Heavy metals present in tap water are also rendered harmless. Use this product at start-up or when changing aquarium water.

Seachem Prime dosing advice

Use 1 cap (5ml) per 200 liters of new water. For smaller amounts, use 1 turn of the cap thread as approx. 1ml. It can be added directly to the aquarium, but it is preferable to add it to the new water first. A sulfur smell is normal. At exceptionally high concentrations of chloramine, a double dose can be safely administered. To make Nitrite harmless in an emergency, 5x the normal dose can be used. At a water temperature of > 30°C and low concentrations of chlorine and ammonia, half a dose may suffice.

Available in: 100, 250 and 500 ml

Doet wat het moet doen, onveilig kraanwater. Veilig en vis vriendelijk maken. Ook veel inhoud dus je kan lekker lang mee!

Bij nader inzien had ik beter 250 ml moeten bestellen ipv 100ml scheelt financieel veel €euro’s
Het product werkt zeer goed kan het iedereen aanbevelen

Bedankt Azaqua voor de snelle service binnen 24 uur in huis

Tot nu toe gebruikte ik direct kraanwater, maar met prime is het toch veiliger om alle chloor te deactiveren.

Ik heb nu vo2 bazooka (diffuser) en die moet ook elke maand ongeveer in een chloor badje. Met prime weet ik dat het veilig is om het na het neutraliseren van de chloor, de co2 bazooka weer in mijn aquarium te doen.

Werkt tot nu toe top!
