Feeding Growth foods

[poohbear]

Currently have 5 tosai that I want to grow out and fed Hikari Staple and slowly switched to Hikari Gold. Recently purchased some Saki-Hikari Growth to grow them out this summer.
Would you recommend mixing both Hikari Gold and Saki-Hikari Growth? Or should I just feed Growth during the summer season and go back to Gold/Staple during the fall and late spring?

One of important things to do when doing a koi grow out, keep your feedings staggered thru out the day like smaller amounts every 2 hrs if you don't have someone to do the feedings consider acquiring an auto feeder. Concerning the foods someone will chime in.

Look for crude protein on the label, my fish like Saki-Hikari, I don't like the price. Alternatively Blackwater and Nijikawa has similar content but at cheaper price, you can consider.
I would just let them do the high protein diet during the warm months and switch back to staple if water gets below 60F, under 55F they don't digest too well and come out as more poop, so I feed less.
