DIY Koi Pond Filter

The pond is done along with all its additions - 1 turtle, 4 floating rings with water hyacinths, and 4 raised pots with rooted "water lilies". The church will only "allow" the filter and u.v. sterilizer to run from 8-5 everyday to save on electricity so the pond will always have a slight green tint and some clarity issues, but overall it is clear to about half way down as is with weekly backflushing of the sand filter and a 10% or so water change.

 

The pond contains around 15 or so 6-8" koi, 8 or so 3" koi, and 6-8 smaller koi. All of the smaller ones except 3 are babies of the adults. The koi and the turtle subsist on a diet of koi pellets, munching on the water hyacinths, eating zoo plankton, daphnia, and bugs that fall into the water.

 

Pics will eventually follow when they are eventually taken and uploaded. 

 

The only things that have not been thoroughly completed are the concrete hollow block wall and gate that are planned to surround the 4 filter drums; a roof for said enclosure; and landscaping around the pond/fountain. These will eventually be completed but who knows when? The fountain/pond is in dire need of a repaint also. Note to all - do not use cheap paint!

 

All funds and labor have been donated for the project as is the (ongoing) $$ for the electric bill and water bill.

The bad news is that no, there are none yet. The good news is that I have access to a camera and should have some pics here within the next couple of weeks.

I almost forgot to mention the u.v. sterilizer/filter. It is rated at 40 watts @ 220 volts and is the largest we could find. It was ordered online and shipped from Manila. It definitely helps clarify the water of the pond and is good at killing algae but only if it is allowed to run 24/7. The church does not allow this luxury in order to save on electricity (the pump, not the 40 watts that the u.v. draws). The agreed schedule for the pump and u.v. to run is only from 8-5 everyday, which sadly is not enough to get the water completely clear.

Since the price of city water is ridiculous here in Dumaguete  (90 centavos/gallon!) it is cost prohibitive to do large water changes so we will also be constructing a very large water catch system.   

That's around 250 php per cubic metre. Are you sure?

Yes, it is.

Are you really surprised? 

Excellent thread. Thank you so very much, for taking the time to keep it updated.

Yes, it is accurate going by the last bill I checked. The price of city water here is outrageous, but the water company here is not owned by the city. It is owned by a for-profit company. 

 

Anyone with a pond or a large demand for water should really consider a rain water catch system and a well. Both dramatically reduce the overall price of keeping a pond. 

 

Ideally a pond and/or aquarium should have weekly 10-20% water changes to reduce nitrates. This is over and above evaporation. The pond in the pictures contains close to 4,000 gallons including the water in the filter drums and the two upper basins. It is common for the water level to drop 1 inch a week in hot weather due to evaporation. 1 inch equates to around 100 gallons. 

 

We have two 50 gallon rain barrels which is sufficient in the rainy season where two to three 10% water changes a week are possible, but they offer no help in the dry season. They are kept lightly stocked (2 per drum) with juvenile koi (1-3") to keep the mosquito population under control. 

 

When the president of the church gets tired of the high water bill he may opt for the installation of more rain barrels or a catchment system. The roof area of the church is huge and even during a moderate rain 100 gallons going to the rain barrels only takes 15 minutes or so. That is only off of one roof slope and one section of rain gutter. The church could very easily harvest 10 times that amount if only half of its rain gutters and downspouts are plumbed to catch rainwater.
