Well, it looks like I am going to redo my ponds in my backyard & I am not 100% sure what to do. Anyone have any suggested websites to read up on what I should/shouldn't do?
I know Joel has lots of experience here..... any thoughts on what I should do with filtration?
Presently I have 2 ponds & a 30-40ft stream connecting them with no other filtration. We are tearing up my backyard to put pavers down instead of the old wood deck & I figure since the backhoe & all that crap are going to be there...... I might as well make the ponds bigger!!! My thought was to keep the top pond the way it is, about 12ft x 15 ft & put all the fish from the lower pond in there (minus the bluegill). With the lower pond, my thought was to have the upper pond have a waterfall (it does now, just goes into a stream) that would go directly into a 20ft x 10ft & 3-4ft + deep pond with a 3-5ft long, 2-3ft wide (so it can go under my bridge) & 2 ft deep stream connecting to another pond which would be 10 x 30 ft (all kinda rough estimates). The top pond I will keep the same size just replace the liner & possibly make it deeper.... it's 2 +ft deep now.
I am not sure on what I should do for filtration & also what type of flow is needed to make koi happy. I see there are sand filters similar to what is used in pools, are those a good idea? Or should I just use lavarock & other stuff like that to work as a filter. I figured I should probably do a bottom drain on each of the lower ponds & possibly one on the top pond. I was told .5 turnover a hr, is that correct though the filter? I was planning to add a skimmer to the lower pond......
I want to keep power consumption at a minimum (also setting up a 475g FO tank inside) so I hope to use effecient pumps ...... not power hungry external pool pumps. I wasn't sure how a simple bubble plate would work in the 2 lower pond area to help with flow/circulation ........
any help/info would be greatly appreciated!!!! I would say the majority of the ponds will get direct sunlight during the day & also..... there will be 3-4 dogs that will probably take daily baths in there......
thanks for any input!!!
