I don't have a lot of koi in my pond - which is about 50tons (measures about 22 ft x 14ft x 7 ft deep) - but they are big kois.. 70 to 90 cm range and about 15 of them. I still have three fishes at the koi farm and probably will bring them back later. I intend to reduce to 10 or 12 kois in my 50 tons pond. I use an autofeeder which feeds up to ten times a day but small quantities each time. You can set the timing of feed and I tried that and set it to 10 secs per feed. That way, the loading on the filter is spread out... and there is time for the filter to manage its nitrification process with a smaller load each time.
I noticed that jumbo koi grows fast and the colour stretches out...(once it gets beyond about 60cm and for Sakai, Momotaro fishes, they grow very quickly... also with my feeding regime).... no doubt, the colour will return if the bloodline is good... but just didn't want to risk colour fading too quickly... i feed colour food once after every three to four bags of Built-up. If your kois are growing quickly in a big pond, you need to maintain the colour. Sometimes, after 15kg of colour food, the shiro does take on a little bit of yellow but it would be gone once I switched back to the normal feed. However, I found out that the whiteness of the shiro is also very much dependent on bloodline, quality of fish as well as quality of water and the dissolved oxygen level. Also, recent years have seen so much changes in the bloodline development, nissai kois can now reach up to 70cm and beyond with some tosai getting a high 40cm and some rare ones going up to 50cm. This rapid growth, I believe, will cause the hi to stretch a lot more... and I am not taking chances .... so, a cycle of colour food is precaution to hopefully, keep the hi intact in their growth process
