Hello Patrick,


looking good so far!

Can you give please more information about the DN100 flexible tubes you guys used for
the filter pipe installation? What the brand of these pipes and maybe where are those to get?

Is not DN100 but DN110 internal size, the pond will work with airlift, the problem was the distance between the outlet of the biological filter and the return to the pond, so i make a outlet collector, the size of this collector is 1m x 1.5 and 2m depth so 3m³, the collector is placed at a strategic place to distribute the 6 return to the pond with 6 airlift driving, I put 7 110 pipes to feed this collector from the biological filter

I hope that you understanding the Principe ?

Thanks and thumbsup up for the next steps!
