Hello
can anyone give any suggestions on how to bring down my
nitrate levels down?
my pond = 11200l
15 medium koi ,to large one being 65cm +- 4.5kg,the other
3.2kg 54cm
.45watt pool pump and koi sand filter, two large bio filters and a five foot uv light,a bottom drain to take away the waste .I flush the pool filter once week.
i have removed six koi since winter.
AS i see it ,i have less fish than i did last summer,now we going into summer again and my levels seem to high and growing.I have given my pond two 50% water changes .
what else can i do ?
