Does anyone have success in keeping coral reef tank with just tap water?

[Flash]

a discussion people on here have had many times! yes. i only use tap-water my reef tank is fine! search around and see what you can find.

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. Without issue

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.

Yes. Never have, never will use RO/DI.

Treat with prime or aqua vitro and thats it.

I am anti-RO.

6 years and counting, no tap water issues. No algae blooms thats everyone swears I should have.

Marketing convinces people that its required.... so do sales people. Lots of hooey.

Tap water is fine.

Here is a link to a poll I posted. More people NOT using RO.

You sure about that? I count 26 to 12 overall in favour of RO and zero "deluxe" systems with tap water....
