So to start i have got my self 3 stackable container made from food grade plastic which are 2foot x 1 and a half foot x 1 foot


Then it was out with the bottoms to alow the water to flow between crate and then in to the pond.


As you can see i have left a strip for exter suport as it will be holding some weight as i am hoping to use about 75 liters of Cryistal Bio, It was then a case of cutting the filter grid sheets to size to fit in the bottom,

Insted of a spray bar iv gone for a spray ring as the area was to wide for 1 bar to go across and give good water coverage over the media, I only have the pic of this so far so i will be updating as i go along,

I still havant worked out quite how it will return to the pond weather i cut the bottom out of the bottom creat and have it flow straight in or make a lip of some kind for the water to flow off in to the pond (Any ideas welcom
