Liquid bacteria to restart a pond filter, 30 ml per cubic metre
The Kido Filter Boost bacterial activator for pond filters is a liquid of live bacteria that is poured undiluted into the filter, at a rate of 30 ml per cubic metre. It is used to kick-start a new or freshly rinsed filter, or after a large water change. The 500 ml bottle treats 10 m³, the 1,000 ml bottle treats 20 m³.
This bottle contains live bacteria in suspension, which you pour straight into your filter without diluting. The dose is 30 millilitres per cubic metre of water, that is, 30 ml per 1,000 litres, and the two bottles are designed for ponds of 10 and 20 cubic metres.
🔄 The day the filter restarts
A biological filter cleans the water thanks to the bacterial colonies attached to its foams and its media. These colonies are absent from a new filter, and they weaken when you rinse the foams too thoroughly or replace a large part of the water in one go. In all three situations, the filter keeps circulating the water while its biological side hardly treats anything, which explains the haze that often appears in the following days. Pouring in this liquid when you restart brings a population of micro-organisms to the place where it needs to settle, and shortens the period during which the filter runs without purifying.
🧴 30 ml per cubic metre
First work out the real volume of your pond: length, width and average depth in metres, multiplied together, then by 1,000 to give litres. At start-up, add the dose 5 days running. After that, maintenance is limited to one dose every 2 weeks, with an extra dose each time you clean the filter or change a large part of the water. Always pour the liquid into the filter, onto the foam media or into the first chamber the water passes through, since that is where the bacteria find a surface to colonise. If your water is already heavy with sludge, the article on cloudy water explains what is going on before the bacteria can change anything.
Tracking the filter's recovery with the ammonium test
A filter that is restarting is monitored with the ammonium test: once the ammonium level drops until it is undetectable, colonisation has taken hold, well before the water becomes clear again. Buy this test at the same time as the bottle, because it is what shows you the effect of the starter series on your pond. To keep things going for the rest of the month without having to dose anything, the bacteria beads are placed in the filter just once.
🌱 In aquaponics
In an aquaponic system, the biofilter plays the same role as a pond filter: the bacteria that settle in it convert the ammonia excreted by the fish into nitrites, then into nitrates that the plants absorb. As the product is harmless to fish and plants, you can pour it into a system in production. Calculate the dose on the total volume of circulating water, including the fish tank, grow beds and sump, and add it at the biofilter inlet. The guide to the nitrogen cycle in aquaponics details each step of this conversion.
📦 What a pond uses
The right bottle depends mainly on the starter series, which uses 5 doses in one week. On a pond of 4 cubic metres, that is 4,000 litres, one dose is 120 ml, so the starter series needs 600 ml, more than the small bottle contains. The 1,000 ml bottle covers this series plus 3 maintenance doses, which is about 7 weeks of treatment. The 500 ml bottle is better suited to maintenance only, or to a full start-up of a pond of 2 cubic metres at most. An unopened bottle keeps for 24 months between 10 and 25 °C, so you can save the remainder for the following season.
