Koi Breeding!! Help!

[tranquility]

I just want to make sure your doing water changes to keep the ammonia and nitrites from going off the charts....after a spawn I do 25% water changes every other day for about a week....spawning will reek havick on your water quality....It takes me a couple of weeks just get the ponds back in shape after a planned spawning....I can't imagine having to get 250 gallons with koi in it back in shape after a spawn... My advice would be to get those water changes going and keep a close eye on the water perimeters....

I already moved some into a tank, with air and heating. Planning on doing some water changes in 24-48 hours depending on water quality.
