TOG, I've NEVER heard of PH solution "degrading" water and causing bacteria to form. PH-Down is an acid and PH-Up is a base. They simply change the alkilinity of the water. Now, having properly PH'd, nutrient-rich water can certainly be a breeding ground for bacteria, especially at high temps, but it's not the PH up/down that causes it.
Also, I don't believe the 24-hour dark period before harvest will effect your yield at all. The reason some people do the dark period before 12/12 is that SOME believe it will trigger the plants to start flowering ealier.
I hope that helps!
