Algae Bloom in the Koi Pond

Koi Pond June142015The electrician came during the week and got my Sequence 9700 pump up and running.  Initially the water began to clear, but because I was running two much smaller pumps, I think I had an algae clog in the end of my grow bed piping because the bed wasn’t filling very fast and the pond continued with its wonderful shade of green.  I realized it was clogged and was able to clear it with a change in the pressure and water flow.  Now the pond is cycling quite well and I am hopeful that over the next 48 to 72 hours it will begin to clear up so we can see the Koi.

The ducks are loving the pond and have been fun to watch, but they keep eating my plants.

Listening to the sound of the water and the quack of the ducks is really one of the most relaxing things I’ve found to do while sitting on my porch on a Sunday afternoon.

So, now as the water cycles and begins to balance itself, the next step is to finish bringing in the boulders, rock and landscape the perimeter of the pond.

Progress on the Aquaponics Koi and Duck Pond

The project that I thought would only take two to three months is now on month eight.  But I have learned a great deal and lost a few pounds in the process.  Here are the pictures of further progress since the liner and stones have been placed.  I am still waiting for additional stone to fill in the gaps.

IMG_1539IMG_1537I placed the liner and after a rain storm and irrigation lifted the liner and rock in the base, I decided filling it would hold it in place much more effectively.

Bottom drain bubbler was inserted and the water filling began.


I put pea gravel into the grow bed and bog areas and while waiting for the electrician to finish the wiring on my big pump, I temporarily inset my small aquaponics pumps into the swirl tank and skimmer to get the water moving.

The ducks love it. So do the dogs.


I found some water lillies and horsetail at Home Depot and added them to the  grow beds to get things started.

 I’ve included video below explaining how the pond works.  Little by little it is getting completed.

Levels and Liners

Had some time last week.

Took time to shore up the walls, smooth out the rough areas, and level the bottom.

I pulled out the underlay material and my son and I lined the pond bottom in preparation for the rubber liner.

Prepped the bottom drain to make it easy to attach the liner by taping over the screw holes ahead of time. . . learned this little trick from The Pond Digger (Thanks Eric Triplett!!)

IMG_1480I called up my family and coaxed them over to the house to roll out the 700lb liner . . . Stay tuned for the moment of truth.

Pond Persistence

I’ve been working on this pond now for the last four months.  Little by little it is taking shape. I never realized it would take this long, but I have learned a great deal about pre-pond design, making walls, plumbing and filtration.

I placed my bottom drain, swirl filter, skimmer and found a large water trough to use at the top of the waterfall.  The swirl filter was designed by cutting the top off a 55 gallon barrel below.

Once the filter was placed, I filled in the area and this is what it looks like from the top.

With these pieces in place, walls have been shored up and the waterfall base has been built.  You can see the skimmer in the center of the image.  I was impressed with the Helix Skimmer from The Pond Digger.  I got my bottom drain plumbed, concreted in and smoothed out.  You can just see it (bottom drain) at the base of pond (I’ve got it covered with a piece of underlayment.)

I decided on the Koi Toilet from The Pond Outlet and I’m hoping that the 4″ drain will accommodate for the ducks.

The The Pond Outlet has a much better image of this bottom drain that I included below:

I’ve reinforced the waterfall base with cinder block and used a 100 gallon water trough as the waterfall collection tank.  this way I can plant some plants in the top of the trough that will further hide the waterfall.

So, the next step is to begin laying the underlayment to protect the liner from holes.  Stay tuned . . .
