Did the alum treatment clean up the water when you did it? How far could you see in the water 24 hr after the treatment?

Don't leave the aerator off too long, if you do, you will have to start it up gradually again - 15 min day one, 30 min day two, etc. If it was my pond, I'd leave the aerator going, if you used enough alum and have the banks covered in grass, the water will clear by itself after spawning is over.
