a cool and soothing atmosphere
Been a while since I posted anything on the koi pond, thougt I’d just show you noobs how sweet it looks now and explains a little about the koi pond filteration system that I had set up. The filter system is designed to require very low maintenance, and at the same time, provide a superb condition for koi to live in.
But first, lets take a look at a couple snaps I took of the pond. The plants are now growing pretty tall as compared to just a couple months ago. You can compare it with this koi pond post that I wrote a few months back on September, and also this one from August. Huge difference isn’t it? However, the green and white plants are invaded by caterpillar recently and that has inhibit the growth quite a bit. The bamboo lookalike and the red leaf plants, however, has been going bezerk. The bourgonvilla is a new addition thanks to FA.
look at the nice gardening job
the kois grew quite abit too
Now lets get a little more pro and talk about the koi pond filter for a bit. Noobs like you might need a little fishy lesson and KY’s here to provide, worry not.
Koi, like any other fish, produces waste. The primary contribution of fish waste would be ammonia, and kois don’t particulary like their living environment to be of high ammonia content. Which bring us to the why the biological filter is needed: To create an eco system that will consume koi waste and keep the water parameter in safe and healthy level for the fish.
first and second chamber of the koi pond filter
My filter is of the simple and old school 5 chamber variety. The first chamber is the settlement chamber, I leave a small net to catch bigger particles and also left the chamber empty to catch any heavy sinking debris. The 2nd chamber is filled with Japanese mat. The purpose of the mat is not so much filtration of particles, but to provide a surface for bacteria to colonise. The bacteria here serves the purpose of converting Ammonia to Nitrite, which is a bit more tolerable by the kois.
third and forth chamber of the koi pond filter
I had filled the 3rd and 4th chamber with bio balls and bio stones respectively. These too are mediums for which different types of bacteria will colonise and make up the biological filtration system. The 2nd type of bacteria will convert the Nitrite to Nitrate.
fifth chamber of the koi pond filter
Brush occupies the last chamber. I had added this as the last step simply because I bought the brush the latest. Thiese too serve the purpose for bacteria colonization. As to which type of bacteria thrives best on which surface, I don’t have a simple scientific way to find out. Then again, my filter system works just fine, with healthy water parameters.
plants to soak up the Nitrate
So, if you’re following me, the Ammonia is converted to Nitrite, then to Nitrate. Well, the kois don’t really love Nitrate either, though they tolerate it much better than Ammonia. Hence this is where the plants come in to make the full eco system, apart from the healthy coating of algae on the wall and bottom of the pond, I have added a few rooted money plants to soak up the excess Nitrate. As a bonus, they are rather asthetically pleasing, I am trying to grow them around the water fall area.
flushing the filter
To keep the pond clean, I simply flush the 3 bottom outlets of the filter for about 10 seconds each daily. Usually in the morning when I feed them. When the flushed water gets to be somewhat green, all I need to do is to shake the filter elements and flush all the dirt out. The process takes not more than half an hour and only need to be done once a couple months.
Awesome, isn’t it? Don’t you wish you have a koi pond too?
