| I've added about 4 new fish to my pond this year and all have died. The pond is about 3 ft deep and about 30 ft2.
There are about 7 fish (Ghost Koi, Goldfish, Comets) who've been in there a couple of years with no problems.
The water is pumped through a UV filter and the water quality looks pretty good - any ideas what could be killing them ?
I suppose I need to get the water tested but is there anything else worth checking ?
TIA,
Mike. |
