Suggestions needed for my inherited pond

Oops I slept in and now wide awake!


Biggest problem for us and the koi pond has been the green algae and getting it under control....but have found a great fix for it.

Do you have a pump/filter etc? If so what type is it? Is the pond in shade/full sun?

How many fish are there?

A great brand of fish food we now use is NT Labs MediKoi...cheapest buying online and lasts a good while.

Do you have any implements to clean the pond and a net?

 

A few piccys so u can see the size of my koi pond-last pic is from the sales brochure (its a little different now!)
