@GBBUDD Thank you, I watched the Ohio Fish Rescue Video on Aquascape, WOW! that was quite a project, this indoor fish pool. Do you have the link or the name of the other video of the homeowners wetland filter built lower?
Here in Europe they often build ponds like this picture with a "regeneration zone" on the sides of the swimming zone (with or without water pump circulation I think)
I guess many people research quite a lot before building their water features! However, it's always reassuring to get advice from others who went through the same process. In my case, many questions regarding my design, (will it work? Which size this? Which size that ? etc..), but now I'm even more motivated to get started after reading this forums comments (and specially yours).
Aquascapes DIYer of the year, I mean... that's not nothing
