Update 7/10/11
I returned tonight to find this email and the photos below sent by email from France.
‘Hello Peter,
How do you do ?
I’ m so happy with my ERIC filters,the water is so clear and now parameters are good.
I send you some shots,you can see that the water is clear,the deep is 2,3m and you see a crew on the buttom.
Now I’m thinking about to cover the pond for this winter.’
By the way, the water is perfectly clear but there’s a slight hint of ‘green’ to it – you’re looking at ‘KOI WATER’!
Please enjoy the photos of a truly lovely Koi pond.
Waddy.
