Tap water

[BCReefer]

50% of my water changes is straight from the tap. I use straight tap water to do mid week fills and when I do my monthly 25% water change. The other times I use my filter. I am not as worried about our water vs. people in larger cities. I was in Chicago a few years ago. The water was so awful I used bottle water to brush my teeth.

I have had only 1 algae bloom when I screwed up on my Kalk and killed off my Xenia, actually i thought I killed it off. Pretty soon the Xenia will take over my tank. Andrew - I think it is time to learn how to transplant Xenia. Well that is for another thread.

Anyways, I don't always use a filter and I have a 33G tank so if anything will happen it should happen to me.
