OK, I thought that i will share with everybody my ponds progress.
This was my original
pond (10 000L) that i constructed in 2005.
[You must be registered and logged in to see this image.]In April 2007 i decided that i wanted to go bigger...as all koi keepers usually do. The idea was to break the existing
pond wall to expand the
pond with an extra 4 meters in length.
[You must be registered and logged in to see this image.]Here you can see where we knocked the
pond wall down.
[You must be registered and logged in to see this image.]In this image you can see the foundations of the walls. Yeah, please notice the clay we had to go through it took a team of 3-4 men 4 weeks to get to that depth. You can also see the steel rods in the walls... i later discovered that i did not use enough steel.
[You must be registered and logged in to see this image.]This is the completed
pond...just add bitumen and water i thought...
[You must be registered and logged in to see this image.]Here the
pond has been water proofed and i am adding the water.
[You must be registered and logged in to see this image.]It took 3 days for the
pond to fill and then i discovered that the
pond leaks!!!!! 5cm - 10cm a day...I then i fiberglassed my
pond. 3 days into the five day waiting period it started to rain and water got in between the concrete and the fiberglass and tore a 1m section open on the
pond floor.
Within 2days my
pond was full of rain water and decided ...ah what the heck lets switch the pumps on and add the fish. Ofcourse during this period i discovered that my filtration system was way underspecked for a 30 000L
pond.
It rained so hard last year that my
pond remained full untill October 2007 with the ground water being just 1m under the surface.
In November 2007 i decided to beef the filtration up and installed:
4 x 400L vortexes. 2 mechanical and 2 bio logical
2 x 25L ultra zap filters.
1 x Ultra zap Protein skimmer
1 x 30 watt UV
I also added an additional .45 speck pump.
[You must be registered and logged in to see this image.] In Feb 2008 i decided that i was time to empty the
pond and move the fish to their new home in the garage so that i could work on the
pond again. Eugen helped me in moving all the kois to their new home.
I got some labourers in to sand the glass fiber so that we could add another layer on top. With that done, i thought my leaky days was over...WRONG!!!
I found that the swimming pool light was leaking and so i removed it. I also found that a nail pushed through the fiber glass layer about 1m from the bottom of the
pond.. so i had to drain all the water so that i could patch that.
Finally i added the water. I still have a leak of 5mm a day but i am writing that of for the moment as part of my water changes. I am convinced that it is a pipe leaking somewhere as the water level does not drop if the pumps are switched off.
Here you can see my
pond as it is at the momment. I am just waiting for the coupings and cladding to arrive. I did not want to wait with the water just incase history repeated itself.
[You must be registered and logged in to see this image.] There are 3 returns on this
pond. Here are two of them.
