Start Up
Starter for the biological filter Biological Filter Starter
Expected spring 2027
Start Up gets the biological filter of your pond going. A filter only works well when it contains enough beneficial bacteria. In a new pond, after winter or after medication these are (not yet) present, and waste can build up. Start Up gives that start a strong push.
How does it work? Start Up is a mix of mineralising bacteria and enzymes. They break down proteins, urea and amino acids into ammonia and release enzymes that the ammonia-oxidising bacteria (such as in Ammonia Shield) need. These convert ammonia into nitrite, which is then converted into harmless nitrate.
Helps with:
- A new filter or new pond that is not yet 'mature'
- A filter that is slow to start after winter or after cleaning
- A disturbed biological balance after medication
When do you use it?
- At start-up in spring: once
- After medication, as soon as the medicine has worn off
- After a major filter cleaning or replacement of filter media
Good to know: Switch off UV and ozone equipment for 24 hours after dosing. Then measure ammonia weekly and use Ammonia Shield if it rises.
