how do i build a waterfall for my koi pond?
hi!
i have a roughly 2500 gallon koi pond. i built in in September of 2008 and im 15 years old
. i have been using a filter weir since because i didn't have time to build a waterfall before school started
. i have at least 20 feet ( all together) of extra liner and i have 4 pallets of rock. also behind the pond there is a hill andthat'ss where im building the waterfall. i want the waterfall to beroughlyy 3-6 feetLongf and a couple feet wide. i really need help on how toSett it up andbuildd it.
theeasiestt thing to do it to juts make like a "slip and slide" out of the liner curving the sides but thatdefeatss the purposebecausee it would look horrible! i really need to know hot to build it correctly.
also, my pump is 2600 gph. when it goes through the filter and everything else the gph coming out into the waterfall is a lot less correct? its a tetra pond 4000 pressurizedfilterr with u.v sterilizer.
i really need help!
thanksx a lot!
Sounds like a great project!
First thing you need to check is the pump. Find the specs and determine what the GPH are at what "head." As the pump has to pump uphill it will reduce the gph. In one pond that I know of they had to replace the pump because it couldn't handle the height of the waterfall and still put out enough GPH.
2. Are you going to stick the rocks together or leave them loose? If you are sticking them you need to find what is safe to use and what is available. If you have lots of little rocks you may have to think about cementing them together. If you have big rocks you might get away with a series of steps.
3. Either way you are going to be starting at the bottom because water runs downhill and you want to direct it from upper rocks to lower ones.
4. Probably this should go earlier but you need to have some idea of the look you want to achieve. You will put your liner under the rocks over an approximately shaped earth. Try putting it together dry and running some water over it. Play around with it to get the look and sound that you like.
Keep the Water Healthy For Koi Pond Fish
Koi pond fish keeping generally turns out to be more of a water keeping and cleaning hobby than it is a fish keeping hobby in terms of care, maintenance and upkeep of Koi ponds. Now at first glance, this may sound a little strange to you as one does not necessarily get into the hobby of keeping and caring for water, but if you think about it, it does make sense when you consider the environment you are creating for your Koi fish is all about, you guessed it, "water".
Koi health is highly dependent on the quality and stability of the water in which they live. With that said, it is worth understanding that clear water does not necessarily mean healthy Pond Water for your Koi, and the reverse holds true as well.
Having recently spent time at a new Koi pond fish development, I had the opportunity to consult with a very worried owner. Her pond had low (but measurable) levels of ammonia and nitrite, and at the same time it had a good amount of unwanted algae growing in it. As it turns out, the water in the pond was passing too fast through the pond filter's UV Sterilizer. Instead of killing the algae, the UV portion of the filter system was just lightly zapping the algae. In other words, instead of killing the algae, they were simply getting a tanned before returning to the pond water for further growth.
It is worth clearly understanding here that in order to adjust this glitch on a manual labor scale, we would have to replace 1/3 of the pond's water. In terms of your Koi pond fish, that's a huge and drastic change in a relatively short amount of time. Imagine if you will being put into a small airtight room. Now imagine someone taking 30% of the air out of that room and at the same time, the room gets smaller by 1/3. I'm feeling a little tight just thinking about it myself.
This kind of adjustment for a new pond would be extreme and was not advisable to say the least. A lot of things, on multiple levels of development, growth, stability and balance, are going on in a new pond - the bio media within the bio film are trying to progress and cultivate to optimum levels of efficiency among other things. One-third water change on a weekly basis is far too risky because with new water, you stand the chance of adding a lot of unknown elements and organisms that might affect the life and well-being of the Koi pond fish living within it.
In cases such as this, it's best in this particular instance to just let sleeping dogs lie and leave well enough alone. It's more important for the new pond water to be giving time, with patients and a careful watching eye, to reach stability than for it to look crisp and clear right from the start. Wait for stability to set in among all of the bio functions going on in the water; then clean later if it is still necessary.
