Questions and answers

What is Levende Pumella?

Pumice that has been matured in fishless tanks until it is full of living bacteria. The stones are in a mesh bag that you put straight into your aquarium filter. We test every batch before it is sold.

How much do I need?

The rule of thumb is litres of Levende Pumella = grams of food a day ÷ 0.7. An aquarium fed 3 g a day needs 4–5 litres. See the calculator.

Can I add all the fish at once?

No. The fish are added gradually over a couple of weeks, and you measure ammonia and nitrite 2–3 times a week for the first 14 days. The bacteria grow with the load.

Should I rinse the stones before use?

No. Never rinse the stones under tap water. If the bag needs rinsing later, use water from the aquarium.

Where in the filter does the bag go?

Put the whole mesh bag in the filter after the filter sponge, and make sure the water flows through it. Do not open the bag.

Should I take out my old biological media?

No. Leave it in the filter and put Pumella next to it.

How do I keep the bag until I get home?

Put it in the filter on the day you collect it. For the journey, keep it cool and dark, not in a car in the sun and not below 5 °C. ”Use by” is on the bucket.

Can I use medication in the aquarium?

Wait with medication for the first two weeks, and always read the packaging first. Some products harm the bacteria.
