Nitrifying Bacteria — 300 ml Water Treatment

Live nitrifying bacteria in a dosing bottle — for cycling new tanks, recovering filters after medication, or backing up a tank during an ammonia spike. The biological filter in a bottle.

• Cycle new tanks faster. Seeded bacteria shorten the dead time before fish go in.
• Ammonia and nitrite backup. Dose during spikes or after deep filter cleans that bruise the biofilter.
• Shake and dose. 10 ml per 50 litres for maintenance; double for new or stressed systems.
• 300 ml bottle. Enough for a full cycle plus months of top-ups on a mid-size tank.
