Which concrete blocks to use and return pipe positioning
Hi looking to plan a 4500g pond build. What concrete blocks do you recommend to use?
Also looking to have 3ft below ground and 3ft above ground. At what level would you have your return pipes and would you have 2 return pipes one from either end running from the same pump? Thanks

I didn't use any concrete blocks at all.
