Hope not. Ever since I started my ity bity pond that I received for my birth day I have wanted a mostly above ground pond and I knew the minute I saw your pictures of your bog garden/koi pond I wanted to do something similar to that. and plant the bog with taller plants to act as a "fence" Here's where I have a few questions:
If I was to build my koi pond a bit smaller than yours (around 8 ft long 3 ft with 4 ft or 5 ft deep with one foot under ground) how wide would I need my bog to be?
I planted all my plants in my current teeny tiny 60 gal pond in pot's with Joyce's soil and I have had a FANTASTIC experience with my first summer in my first pond. I would like to continue to see the crazy growth I get with the soil but the bog's I see are all made of gravel and rocks... Can I ... IDK line the bottom with rocks, the sides with gravel (about 3 inches thick or so) and fill the center with organic compost? or will that defeat the point of the bog?
are you happyer with the seeping cinder block wall or the water fall?
My other idea is to build something like this:
-----------------------------------------------------
l l
l l <--- This entire section would be the bog
l l
l l
-----------------------------------------------------
l l l l
l l l l
l l l l
l l l l <---- these 2 areas would be my pond section's
l l l l And around the inside I would build a
l l l l bench. This entire area would be
l l l l between 2 sheds in my back yard creating
l l l l a cubby. I thought from there I would
l l l l take lattice staple some sheer fabric to
l l l l one side of it and simply set it on top of
------------ ------------- the sheds and allow the fabric to hand down the sides too thus hiding the ugly exterior walls of the sheds and shielding the ponds from birds, oak tree leaves, and making it pweety

In my second idea I would use 2 smaller pumps (one strong enough for each side's volume to cycle once in an hour so the pond would essentially cycle 2 times per hour) in this plan I would use way more lumber, way more liner, but I could possibly keep either goldies in one side and koi in the other or use one side as a lilly garden and the other for koi.
Now as far as my old insy winsy pond goes I plan on turning it into a bog / guppy pond. I am hoping I can simply fill it with compost and water about 5 inches above the soil put 2 inches of gravel and release the guppy's... will that work?
