Koi pond! Really confused.

[GBBUDD]

I'd only use it as a fine filter if i had a bog to go with it . or i'd fill it full of K1 and use it as a bio ifi didn't have a bog

In that case I guess the question would be. Im I better off using 1 stronger pump having it flow through everything such as Biofalls, Pressure filter and bog or Im I better off having two seperate pumps. Considering my skimmer has a mac flow rate of 5000gph.

Must I build a retaining wall for my waterfall?

Also wanted to confirm that my bog has to be on a slope going towards my pond, meaning back of bog is higher then the actual pond correct?

Many people recommend two pumps for redundancy - if one fails, you won't be completely shut down. We run on one big pump and to be honest did have one situation where a second pump would have been helpful. But since we really have only one plumbing line (keep it simple theory) that runs in a big loop, adding a second pump didn't seem like an option.

Are you pumping from a filter to the bog?

I mean I can do it however makes the most sense. In my head I figured I would do a mechanical filtration filter to get rid of wtv debris before going in the bog which acts as the biological filtration.

I can also do Skimmer to bog using pump in skimmer and filter to biofallls using pump in pond. If that makes more sense.

 

[Lisak1]

Skimmer to bog is the usual set up- you want the water to be clean (free of debris) but dirty (full of nutrients) for a healthy, fully functional bog.

Makes total sense given the skimmer also cleans up debris.

So I think I will do
-Skimmer with pump to bog

-Then Ill do submerged pump to filter then to Biofalls. Should I fill up my filter with Bio media or make it mechanical?

Personally with a bog I don't think you need more biological filtration.

My only concern would be I dont think my bog will be exactly 30% of my pond. It will.most likely be around 20%.

 

[Lisak1]

Honestly that 30% is just a wild guess. Ours is probably more like 10 - 12% by surface area and functions great.

I'VE BEEN questioning what i have been doing building the monster bog. the small pea stone i have has kept the pond well, water is clear

You were bored....

Been a little bit , Hows everybody doing?

So Ive established my area , Ive measured out the pond. It will be 14 feet long by 8 feet wide by 4.5 to 5 feet deep, I will have "shelves" ect.. I estimate the pond should be around the 3,500-3,750 gallons.

My liner is ordered and on the way , should arrive May 8th. My biofalls is expected May 5th, my pump is expexted today. I already purchased/have the underlayment needed.
