soooo... really? 0 PPM on the water?
Nope it is not 0 PPM since it is tap water but I was not going for 0 PPM. I have been using tap water since I started as has everyone else here in Iceland and my corals are outgrowing my tank.
Here are some numbers from the water source (Sorry about the formatting)

I ran these numbers by Randy Holmes-Farley to see if the water was good a while ago and he said he saw nothing wrong or abnormal in those numbers.
