Contents

Water changes & spike rescue

Two jobs, one bottle

A routine tap-water conditioner most of the time — an emergency detox when things go wrong.

WHAT IT DOES

Renders tap water safe

Chlorine and chloramine are common in tap water; ammonia, nitrite and nitrate build up from fish waste and organic decay. This detoxifies all of them before they reach your tank.

WHEN IT MATTERS MOST

Ammonia & nitrite spikes

An inhabitant death, a pH swing, or another major parameter shift can spike toxic ammonia or nitrite fast — the emergency dose can buy you time to fix the underlying cause.

HOW TO DOSE IT

Dilute, then add to high flow

Dilute with aquarium water first for direct dosing, or add slowly while mixing into your water-change container.

Dosing

Cannot be used on a dosing pump — dose manually.

Step	Amount
Routine water changes	5mL per 300L (79 US gal) of tap water
High chlorine/chloramine	A double dose may be used
Emergency (ammonia/nitrite spike)	Up to 25mL per 300L (79 US gal) of aquarium water

Questions about this product

When do I need the emergency dose instead of the normal one?+

Use the emergency dose (up to 25mL/300L) for an ammonia or nitrite spike — commonly from an inhabitant death, a pH swing, or another major parameter shift.

Can I run this on a dosing pump?+

No — Water Primer™ cannot be used on a dosing pump. Dose it manually, diluted, into high flow.

Is this the same as Water Stabiliser™?+

No — Water Stabiliser™ is for cycling a new tank with beneficial bacteria and nutrients. Water Primer™ detoxifies ammonia, chlorine, chloramine, nitrite, nitrate and heavy metals, including in an emergency.

Water Stabiliser™ is the one to reach for first.
