Please try and bear with me as this is my first koi construction project. I am in Central Florida and plan on building a pond that is a mix or recreation and to possibly raise a few koi for show as a hobby. I will be building a 12 by 8 pond that is 3 to 4 feet deep through the use of large lumber, liner, and a lot of hardware to support its weight out onto the walls. I plan on having a small upper level of small stone and plants to have my water return to and then flow down from it using multiple water falls. Right now I am looking for recommendations on my pump and filter. I do not want to invest in a huge system yet as this is still a young hobby. I was thinking of a SICCE Green Reset 40 with a submersable pump of up to the max 2200gph the filter can take. The pond will get a mix of sun and shade and will have probably 10-20 koi in it max. The pump would also have an additional inlet so I can hook a skimmer up as well. Any thoughts on my filter? Any suggestions?
