New Koi pond build...any assistance?

[addy1]

Nice looking! My ponds are in full sun, the bog keeps the water crystal clear, never get the "dreaded" green water.

Addy1 Are you using a UV as well? What type of plants are you using? I'm wondering if my water is moving to fast also. I have a 4200gph pump moving thru about 27' of 2" pvc of which about 19' are in the bog

No uv, I have never used one. My pump, discounting head pressure loss which is not much, is rated at 6800 gph. I have two , two inch lines running below the pea gravel. Around 25 feet long.

I have yellow iris, obedience plants, marsh betony, creeping jenny, lizard tail, blue forget me not, spiderwort, other iris, bog bean, water willow and other stuff that I can't think of right now.

This is the bog

   I've recently started renovating an old in ground cement pond I found in my yard buried under dirt rocks weeds melon patch etc. it was a heart shaped pond but after 2 winters kept cracking and leaking so I decided to rebuild it, it's 2' deep currently and I'm going to build it up with 4x4 timbers another 2' for a total of 48". I plan to dig out the dirt portion and add a four inch bottom drain which willgravity feed into a 55gallon drum which will be used for a settlement tank. Waterwill then be pumped into 8'x3'x12-15" deep bog which will stream/waterfall 3-4' back into main Koi pond. Pond will be pentagon shaped with average width being 11' across....

Looks like a great project I look forward to seeing it finished

Only comments would be shade, if you are going to put fish in the pond then they will need part of pond to be in shade all of the time.at least 10 sq ft.

Also if the cement or concrete is in contact with the water then it will get very alkaline. Make sure the ph of your water is steady at 6.9 - 7.5 before putting fish in.

Yeah I used a pond liner over the cement and I'm working on how to add some shade to the pond, I've some lily pads growing currently

 

[addy1]

My fish get shade as the lilies grow. But they do not spend a lot of time under the leaves, they prefer the deep lily less end.

I wish now I had made my pond a little longer

 

[addy1]

Mine is around 27 feet long.

This is the current lily coverage the fish hang out in the open area to the right. That area is around 5.5 feet deep.

A couple things I would change are the timber walls and the 4" bottom drain.
Timber will eventually sag and rot, I would go with a concrete block on a firm footing.
Also the 4" bottom drain is too big for your pond and settling tank. You will never get enough flow through a 4" bottom drain to adequately carry debris and solids to that small settling tank and then hope for the solids to settle out. I have a 3" bottom drain with a water flow of 3000+ gph and a 110 gal settling tank and I have a bit of a problem getting solids to settle in my settling tank.
If you use a 4" bottom drain and don't have enough flow you will get solids settling in the pipe going to the settling tank. Go with a max 3" bottom drain.

That's funny because I went back and forth between the 3" and 4" for the longest time and finally from everything I read went with 4" and the last minute, I did add a second 55gallon drum one pure settlement and the second is where my pump is. Pump is a Laguna 4200 so hopefully that helps with flow issue. It's my first pond so I figured I would make some mistakes Too late for me to change now pond is running I'll have to wait until it starts sagging and then revamp the entire pond, hopefully I can get 5 years or so out of the 4x4s

I'm losing about an 1" of water in 3 days, for a 10' or so diameter pond is that normal? It has been very sunny for the last week or so

 

[addy1]

i can lose up to a inch a day if not more when the wind is blowing, the sun is out, humidity low. The bog plants use a lot of water also. If I see more than 3 inches gone I start looking for a misplaced rock, plants blocking the stream etc.

I just add water and don't worry about it
