2000G pond and 830G sump (almost)

[ShadowR1]

Hello people. I have been researching bout ponds, sumps and fish for awhile now until I stumble upon this site which educates me a lot. This site together with its very experience and knowledgeable member really opens up my eyes towards the technicality and knowledge of ponds, filtrations and kois. Hats off guys.

I’m planning of digging a pond of 12’L X 6’W X 4’D with a 5 chamber sump measuring 2’L X 2’W X 4’D each. After much reading and brain storming I’ve come out with the idea of putting brush on the 1st chamber, Jmat or green matting on the 2nd, bioballs on the third but with a drip plate on top of the bioballs as the water will drips down the bioballs, 4th chamber is optional as I am not sure I will need UV or heater as it is an fully indoor pond, I am not sure that I need either but I keep my option open and lastly the 5th chamber house 2 pump. 1 to stimulate the water current to the pond and the other is for a water feature.

Please do comment and correct me if im wrong. All suggestion and criticisms is welcome and appreciated.

Thanks

Welcome to MFK!

I'm not too knowledgeable about sumps so I can't tell you if anything is wrong but I look forward to seeing your build. Please keep us updated on how things proceed. Good Luck!

Sorry guys,
I forgot to mention that my options of fish are not concluded as yet and my second choice of fish to put into it is Arapaima. Maybe 2 or 3.

Thanks

great drawing and great idea in order for the bio balls to work as a wet dry don't build the wall between the heaters and pump making the filter four chambers!

Will do, thanks.

How does the water get from the pond to chamber 1 ?

a & b are pipes? the water level in the pond VS sump ?

Many many potential issues...

how bout a side view drawing showing the relational heights of pond & sump (or are they even w each other?

Where I am going is that, if the pond & filter (sump?) are at the same level, then the water level in the filter will have to be the same as the pond or it will not flow chamber to chamber.

The idea of a sump is gravity feeds the system

Also the bottom fed chamber 1 will have issues with the pipes & media clogging & you cant tell because they are not seem (nor accessible)

I am not saying this general design cant work, it can, you certainly need to change the dynamics of the filter to a degree

Hi there, thanks for your feedback.

The water from the pond are being channel from 2 undermount A and B. As this is an initial plan and correction is in the process from feedback, the water level in the pond is the same as the sump.

The sump water inlet piping from the pond is lower, around 6” height so that the water will flow through the brush to the next chamber.

Thanks

Here are some thoughts..

Have the water flowing down in all chambers, extending the pipe to above the brush (pipe extension optional)

Remove the wall between the heater/UV & pump areas no real need for that.

Lower each chambers divider in progression, allowing gravity to work, leave the last wall (bio to pump/heater) high enough to have some water in the bio chamber, even if the pump area runs dry for any reason.

Have the discharge pipes either above water level or with an check valve or siphon break to prevent back flow in event of pump failure. (keeps water going in one direction)

The red area is theoretical water levels.

OK, now I am happy with "your" design
