My pool temperature gets to 90 degrees. and I understand koi prefer the water temp to stay below 80. If the pond is deep enough would they be OK? Thanks for any information. I have built two koi ponds in Tennessee, but obviously Phoenix is much hotter.

yes I just built one in houston tx

you have to dig one part deep so when the weather is hot they have a place to hide. I built a bridge over onside it provided shade and i dug down under the bridge so they would have a cold spot. they have grown very well and dont seem to mind the weather and temp of the water

I am getting a koi pond but no one I know has one my backyard is huge and has several spots.

This a very cheap project for a do it yourselfer. Some basics

1 dig the size hole you need.
2 place a rubber liner in the hole. I use rubber used for roofing.make sure the liner is big enough to lap out of the hole a few feet.
3 place stones around the out side making sure to place a row of stone on the rubber to hold rubber in place.
4 purchase filter and pump system

You now have a pond. Ask around to find out how deep you need to go in your area for freeze.

I have a Koi pond that the Herring came and eat all my koi fish. Is there a way to get rid of Herring from scooping up all the Koi fish in the Pond? Please help…..

surely you mean herons
anyway, the best way to deter herons is to build a slight frame over your pond and cover it with pond netting or fruit tree netting
that will keep the herons out for good

Lately there has been a heron (i’m not sure what sub-species) hanging around our koi pond outside. It has already eaten a couple and i was wondering if there was a way to keep it away due to the fact that our dog (who normally would be guarding the pond) has been staying in more due to it being cold outside. Any suggestions?

Shoot it.

How do I keep the wild ducks out of our outdoor koi pond?

Not being familiar with your koi pond makes attempting to give an appropriate answer a bit tricky. Netting?

i have an 1800 gallond pond that has koi and goldfish. it is two and a half feet deep. i have three submersable heaters and two floating. the water temp is now around 50 degrees F.
when should i turn them on? wait till it gets colder or now.
the submersable heaters are good for a 300 gallon pond, thats why i get three of them

You should get a thermostat to control your heaters. They can turn on when the temperature drops below a certain level.

You probably shouldn’t let the water get below 40 degrees F.

I have a 7ft by 8ft section that I want to build a concrete koi pond but being a first timer I just wanted to get the most advice possible. so far I have a dirt hole with some cynder bolcks around the outside. Also how easy is it to pack in concrete on a vertical wall with no kind of form to pour it in.

Thanks Kevin

I have only seen one pond made from concrete and that one was short lived. They ended up going to a liner. a pond that size would be easily done with a liner. Concrete will also turn green rather fast because of the algae.those cinder blocks would be great for the edging around the top of your pond. you will need something to hold down the liner if you decide to use one. and the blocks also act as a good back drop for any flowers or plants you put around the pond. Have fun and good luck!!!!

I have tried every kind there is. Most chemicals don’t really work. Algae goes through cycles, dying back naturally. So you put in the chemical at the height of a bloom, then when it dies back, you think your treatment did it.

To eliminate green water algae, a UV sterilizer does work. To eliminate hair algae, 1 – 2" blue tilapia fry will eat it all. I put about 20 two inch Oreochromis in my 2000 gallon pond in the spring. They leave the koi alone and like to hide in upturned milk crates that I prop my plants up on. Remove them in the fall, since once the water falls below 50, they cannot take it.

I’m doing research on having a koi pond installed when I buy a house. Average size would be 12′X17′ and 4′ deep, a couple waterfalls and lights. Flexible liner. and all equipment (pump, filter, jets,…)

For a pond that size it will cost between $15,000 and $20,000. Just the filter will cost $3,000. Those will be the basic costs for what you have described and for more landscaping around the pond it will probably be more. Your area of the country make a big difference in the price so some areas may be more. If any contractor would give you a bid of under $10,000 then you should run away from them quickly because they do not know what they are doing.

I have a 1700 gallon koi pond and a new 560 gallon per hour pump for my filtration system. Is it too much? Should I adjust it do pump at a lower rate? At what rate is suitable?

Thanks!!

If anything its too small, but a lot depends on what type of filtration you are running. If its a submersible box filter, that pump will be fine. If you are using it for an external system, water fall, etc, you won’t get enough flow. Remember for every foot of height you go up, you loose 100 gal/hr. The only way to know for sure it to test it out.
