Like I said, I've been running this setup for about a month or 2 constantly and my flow rate is above 350GPH and I've seen no bubbles what so ever, no "white-coats," nor any reduction in water cooling efficiency... And it smells nice too if you have a bong or something like that!

Remember to PLEASE have ANTI-FREEZE in there, cause I don't know what would happen with out it... Probably create a more basic-solution which doesn't attack metals as violently as slight acids tend to do... Plus Anti-freeze (green stuff) has lots of inhibitors in it, so plain distilled water might have diff effects but I'm doubting it... The Lysol is pretty harmless (just an ammonia derivative) and I added a very sparing amount.
LEMONS TO YA!
