My pond is 7000l
Blagdon pump
kockney koi yamitsu 30w UV
Cloverleaf CL2
Its been hectic in my pond lately but there has been problems. My koi were spawning swell as some really bad weather which blew some of the plants blew of the shelf and landed on the floor. The fish started flicking so I used Blagdon anti parasite and fungus treatment which didn't really help so I decided to pickup the plants and do a water change due to the pump collecting a lot of the plant soil. I found some strange unexpected things in the filter which I hope you can help me identify. thank you all so much and can't wait to enjoy this forum.
