I use tap water but I'm going to do the ro/di route down the road just to eliminate tds and such from any problems encountered down the road..

I use tap water. But also ro/Di but I have success. It all depends on the quality of you tap water. Mine has some crap in it so I try to use ro when possible.

Most area's have ground water test reports. Check out your city page and they should have some. You can see what the TDS is, as well as more tests than we run in our tanks. Most places around here the ground water is good, and the stuff that's actually in there is also in our salt mixes, making it very good. I run RODI because after a couple lead and copper pipes I'm worried about my houses contamination in the water.

I always had an algae problem when I used tap water. There used to be a guy on here who lived in the N part of Calgary ( different water source ) who used tap water and prime. He had a nice little mixed reef.
