Well buying a house and getting an old in ground 2500L concrete pond that's full of leaks, had some fish, but no pump or filter, gets lots of sun etc etc, you'd be surprised that I just didn't fill it in and be done with it. Well 6 months latter a pump and filter, LOTs of water and I have 8 15cm-20cm gold fish, some gold some black, and 20-30 young ones in the last month.
Well a new pond became part of the renovation project and over Jan I got to work building it.
As you can see its above ground, around 1800L in the main pool (58cm deep) with a 230L biofilter/swamp in the long box to the left. no sure what exactly Im going to poant in the swamp yet, though leaning to wards using NZ natives and may put some bullies in there as well. There's a lot of landscaping to be done in the future, including a deck around the base. The need to demolish the old pond to put some new drainage in pushed this part of the project to the front of the queue, well that's my excuse anyways
