Sunken Garden Good Bacteria: Liquid Beneficial Bacteria for Freshwater Aquariums

What is Sunken Garden Good Bacteria?

It is a liquid beneficial bacteria supplement for freshwater aquariums. It adds bacteria that support biological filtration, the process that breaks down fish waste (ammonia) into less harmful compounds. It supports the nitrogen cycle in new tanks and helps rebuild bacteria after filter cleaning or medication.

What do beneficial bacteria do in an aquarium?

Fish produce ammonia, which is toxic. Nitrifying bacteria convert ammonia to nitrite, then to less harmful nitrate. These bacteria live on filter media, substrate, and surfaces. When they are missing or disrupted, ammonia and nitrite can rise.

How much Good Bacteria per litre?

Use 1 ml per 10 litres of aquarium water. That is 0.1 ml per litre.

How do I use it?

1. Shake the bottle well.
2. Calculate your tank’s actual water volume.
3. Add 1 ml per 10 L directly to the tank, near the filter output.
4. Keep the filter and aeration running.
5. Dose after water changes, filter cleaning, or medication, or as your label directs.

When should I use it?

• Setting up and cycling a new aquarium
• After a water change (once a dechlorinator has been added)
• After cleaning or replacing filter media
• After a course of fish medication
• In shrimp, planted, nano and breeding tanks

Does it help with cloudy water?

Not directly. Cloudy water has many causes: a bacterial bloom in a new tank, overfeeding, dirty filters, or suspended particles. Supporting biological filtration helps keep a tank stable, but this is not a water clarifier.

Will it cycle my tank instantly?

No. Cycling takes weeks, and bacteria supplements support the process rather than skipping it. Test ammonia and nitrite regularly until readings are stable.

Frequently asked questions

Does it reduce ammonia and nitrite?

It supports the bacteria that process them, but it is not an instant fix. In an emergency spike, do a water change first and test again. 

Can I use it with a dechlorinator?

Yes. Add the dechlorinator to new tap water first. Add the bacteria to the tank afterwards, or follow the label order.

How often should I use it?

After water changes, filter cleaning, or medication, or follow your label. Avoid overdosing.

Can I use it with medication?

Add bacteria after a medication course ends, since some medications can harm bacteria. Check the label of each product.
