I have always wanted to start a pond and I have been looking around online for a begginers guide. Here is my plan. I wish to have a 1750 gallon pond roughly about 10 feet long and 6 feet wide. All of the edges of the pond will have a 2 foot drop followed by a 25 degree angle slope to the bottom which will be 5 feet deep at the deepest. Now this is where my question comes in. Every article I have read says it is wise to use a bottom drain. What in the world do I connect this bottom drain to? Also my next question regards filtration. do I need a skimmer If my filter has mechanichal filtration? also can I use an all in one filter that has both biological filtration and mechanical or do I need seperate filters for each? My final question would be If I used a pump to bring my water to the filter would I need another pump to bring thr water roughly about 1 feet on a 12 degree slope to a waterfall or will the original pump be sufficient? My last question is about how many mature koi can I keep in a pond this size. I know these questions might sound obvious but I am new to this. Thanks
