I have built my first pond.I am busy with the external stream/plant bed.I would like some advice on what aggregates/soil to use as well as which plants I should consider.The plants will be in shade 100% of the time as it is under my house.Only the deep side of the pool gets sunlight.My average water temp at the moment is around 12 degrees celcius.There is really good circulation in the pond.
Do you think my koi  will ever spawn in this cold water?
I can only post pics via Photobucket after seven days it seems.

Hi G-force,

12 degreen celcius is too cold for koi to spawn.
Can I see the newest photo about your pond?
