I have a 5,500 litre pond with 15-20 goldfish, a few WCMMs and plants. Pond is UV filtered. It has been established for about a year and a half. I didn't realise UV bulb need replacing at intervals to keep pond clear. Clarity has reduced recently, although it is not completely opaque with algae.
I have a new bulb on order. Have cleaned filter etc.
Have been told by lfs to not feed fish every day, which I have been doing over summer.
Lfs say feed once a week to help prevent algae.
Will this be okay? Anyone else, with experience of keeping a large outdoor pond with goldfish, have any suggestions? Is once a week okay? I would like to try to develop size of fish over time and also have them in sufficiently robust health to breed.
I wonder if once a week is a not sufficient, especially in summer - they seem sooo hungry!!
Advice appreciated.
Thanks.
