No matter how unclean the holy water looks, it will kill the bacteria and purge the sin. What in the world is better than this?
无论圣水看起来多么不洁，它既能杀菌又能洗脱罪恶。这世界上还有比这更好的东西吗？

You can let the tank go for awhile and not dose to purge any excesses that might have built up over a month or two or you can test to see rather than do the water change.
