| If your source water is good, go for it! From the moment water enters the pond, it begins to degrade. The key is to maintain a regular schedule to maintain stable conditions. If you could do 10%-20% water changes per day, and stock at 2,000 gallons per koi, you would be getting to the point of the best grow facilities in Japan. A lot of folks disagree with the notion of large water changes. I believe this is because they have seen large water changes result in fluctuating pH, etc causing instability in the environment in which the koi are being grown. This is the result of not having a regular schedule. I change about 35% per week altogether. If my pond was smaller, I would try to change 50% over the course of the week. But, the water bill really does mount up. There's an old thread I'll see if I can bump up. |
