    Thanks

    I try to get green water in my fry tanks within the first month, but probably not before two weeks. Need to visually inspect them for the first culling.

    Norms for Traditional Japanese Method for keeping ranchu does not handle any green water. What this means is they do not make any efforts to cultivate green water. If green water happens to develop on its own they will not take any measure to stop it, however during the next water change the fish are moved to a fresh pond and the old pond completely drained, therefore losing all the green water. It is possible for the green water to be seeded into the new pond simply by the water being carried on the body of the fish during the transfer. In wintertime you will see greenwater develop mostly due to long intervals between water changes.

    agree with glassGoldfish! Just to add:
    Green water happens when there is a lot of sunlight. It develops faster when temperature are higher. Just like GlassGoldfish stated, traditional Japanese ranchu methods don't involve efforts in making GW. But it often appears with sunlight and higher temperatures. There are signs to watch for, when raising fish in GW: sudden color change, sudden darkening or clearing. In this case water change must be performed immediately. Also, oxygen over saturation can happen. In all, a good skill and more attention is necessary to balance GW and ranchu rearing.

    Hi, Jeff!

    You said that: " In wintertime you will see greenwater develop mostly due to long intervals between water changes."

    How many days do we actually increase from the usual 4-7 days interval between water changes during the cold season up to spring?
