| I've priced out a submersible pump that goes inside the filter along with the UV light. I believe that I can still add a bottom drain to this system. I still have time to figure this out. I'm not breaking ground on the pond until May 4th. Any advice would be appreciated. I do have background in building inground vinyl pools. I am familiar with installing bottom drains. But, building a swimming pool and building a koi pond is a little different. Thanks again for any help as I am still an infant when it comes to koi. |
