      Is this enough water?

      SOO glad this board was added!

      So I am setting up my spawning tanks. I have planned for three. see my plan below

      <img src="http://img.photobucket.com/albums/v228/surfhead/sideyardlayout.jpg" alt="Image hosted by Photobucket.com">

      Not including water in the filters - 'A' is a 2000 gallon tank where my parents will live year round. I figure about 6 or 8 max. 'B' tank is a 600 gallon spawning tank and 'C' is a 1000 gallon holding tank for the fry. I also have my current pond that is a 1000 gallons as well. I plan to have three females and 3 to 5 males. Probably two butterfly, two ogon and two or three kohaku.

      The 'A' tank will have a 4 barrel filtration system. The first barrel is an empty SC receiving water from a gravity bottom drain, the second is filled with mechanical filtration media and receives water via gravity from the first barrel. An external pump (apx 4000 gph) will pull from the second barrel and send water up to 2 elevated barrel that will be trickle towers filled with bio media. One barrel will flow directly into the pond and the second will feed two TPRs. I will post drawings once I have them.

      the other two tanks will each have a two barrel filtration set up, a SC barrel that has mechanical media at the top. flowing into a second filled with bio media and back to the pond.

      so you think this is enough water to handle the spawn of three females? Or should I stick with just two females? I can easily add more barrels for additional filtration if the water quality becomes an issue, but I don't have the space for more water.

      No! That's not enough water.

      I'd suggest you only spawn one female. You really don't have enough water to handle the fry from even one so don't plan on trying to hatch all the eggs. You should also consider keeping the females and males separate until you want to spawn them to insure you don't have a flock spawn in your adult holding tank. That would really mess up your filtration system.

      You should also consider using the 1000 gallon tank for the spawning. On the evening before you intend to spawn add fresh water to the tank to about 24" deep and place the female and males in the tank with spawning media. The evening of a full moon in the spring when the water temps are around 68F would be a good time. Be sure you don't have any filtration running. Also, be sure you have a good net over the tank to keep them from jumping out.

      At the same time you add fresh water to the spawning tank you should also add fresh water to the hatching tank to 18" deep. Multiple small air stones spread around the tank works better than one large stone. To keep the eggs from developing fungus add some Methylene Blue or Malachite Green to the water. You need to keep the water temp as stable as possible. Once the eggs have hatched and the fry have consumed their egg sack and are at the swim-up stage you will need to start feeding them every hour or two. You'll need to siphon the uneaten food off the bottom of the tank and add fresh water daily. If any filtration is used it must have a very fine pre-filter and low flow. Monitor the water for ammonia and treat with ClorAm-X or other quality ammonia binder.

      Gene, thanks! I'm gonna save your reply!

      I haven't built these tanks yet, given the space is there a better way to do it? Should I try and make the 600 gallon tank (B) bigger so I have two 1000 gallon tanks. One for spawning and one for fry? It will be tight but I might be able to squeeze it in.

      If I only have 1 female, then I don't need a 2000 gallon holding tank. Maybe split that and make the fry tank bigger?

      I figured I would have to cull quite seriously to make this work.

      Gene,

      Maybe I could set up a few kiddie pools just for use in the Spring during spawning? Just a place to hold the fry until I can sell them off. I could have them in the garage where I can control the temp easier.

      Keep the females in chilled water and the males seperate in warmer water.


      Then when the females and males are introduces into the spawning tank. :woo: :fiesty: :woo: :comfort: :buzz:

      If I were doing it I would have two 500 gallon tanks. One for the females (you should never keep one koi by themselves) and one for the males. I'd use one 55 gallon plastic drum filter powered by a Pondmaster 1200 gph pump for each. I'd use a 300 gallon Rubber Maid stock tank for hatching.

      Then I'd put as many 500 gallon tanks as the space allowed.

      every answer brings up new questions...sorry to be a pest.


      ok, so lets say B is the female tank with two females. C is the male tank with probably three or four males (two per female?). Then instead of one big 2000 gallon tank I have 4 seperate 500 gallon tanks? These would hold the fry, yes?

      And the 300 gallon rubbermaid stock tank, this is where I would place the males and female to spawn? (I thought you said I should use a 1000 gallon tank for that) Then once they are done, remove the eggs from the 300 gallon stock tank and put them into one of the 500 gallon tanks. Or do I let them hatch first and then move them? Then as I cull and they grow, they will expand into the other 500 gallon stock tanks and into the kiddie pools I will set up in the garage. I assume the four 500 gallon fry tanks need a 55 gal drum filter as well, yes?

      Does that sound about right?

      I recommended using the 1000 gallon tank for spawning when we were talking about the design you posted. With the tanks the way I propose I'd use one of the 500 gallon tanks for spawning. Once they have finished spawning I'd remove the eggs I wanted to keep to the 300 gallon hatching tank. Then put the female back in her tank and the males back in their tank.

      For the two weeks after they hatch you would need to work every day to keep the fry feed and the water fresh by siphoning the uneaten food off the bottom and replacing the water you remove with fresh water. The extra 500 gallon tanks should be kept full and the water aerated. Use the oldest water from those tanks for the fresh supply for the hatching tank. After the two weeks start separating the fry and putting them into the 500 gallon tanks by size. Keep the smallest in the 300 gallon tank.

      ok, I got it. another post to save and file away. Thanks for the great info!

      So I have the 600 gallon for two females. the 1000 gallon for 3 to 4 males. and four 500 gallon tanks and one 300 gallon stock tank. Use one of the 500 gallon tanks to spawn and keep the other three filled. move the fertalized eggs to the 300 gallon and let them hatch there. feed and clean the 300 gallon tank daily (using the water from the other 500 gallon tanks) and as they grow start transfering them a few at a time, culling as I go, into the 500 gallon tanks.

      If needed I can set up a couple kiddie pools in the garage to handle the excess fry.
