Help.....I had my koi in the garage in a self made pond all winter

. I put them back outdoors last weekend. Water conditions were a little high in PH but fish doing fine. I added about 15 gallons of the water the fish were in into the outdoor pond and then the fish.

This week.....wallah! hundreds of eggs and two koi are still spawning. What do I do now? I really don't care if they all make it to hatch but curious and hopeful if they do. Please let me know if you can help.

Oh gosh. What you've got there is a recipe for disaster.

It's too early in the year for active biofiltration and your fish will be chowing down on the eggs and generating tons of ammonia that your filters won't be able to process.

Get those fish back into the indoor pond with the active filter as soon as they've stopped spawning, do a bunch of water changes and test ammonia in the outdoor pond until it is bearable.

The eggs will hatch in less than a week, and after that, the fry can take care of themselves. Do not put your fish back outdoors until the water is back to zero ammonia, and do not feed until your outdoor filters are up and running.
