It sounds like your pond water is polluted
How to be sure
Your pond has an oily surface or the surface foams after heavy rain or around waterfalls and fountains.
Step 1 – Treat your pond
- Test the water which may highlight pH, nitrite or ammonia change caused by pollutants – treat accordingly
- Perform a partial water change, using Fresh Start, to help dilute the problem.
- Consider adding an air pump to help toxic gases escape.
BE AWARE! – Treatments can sometimes reduce oxygen levels in the water. If your fish begin gasping at the surface you can add an air pump to increase oxygenation.
Step 2 – Support your fish
Blagdon water and algae treatments can safely be used with Blagdon fish medications.
Only use one fish medication at a time.
