Rodi ?

[vadave]

I am setting up a 75 reef. My RODI makes water slow. I was going to buy water at my lfs. They told me to use tap water, that it would not hurt because i will be cycling the tank anyways. I have never heard this befor. I am getting a new RODI in two weeks. So should I wait?

since you have it on the way i would either wait, or by some RO form the LHS or grocery store. you never know what is in your tap water. it doesnt take much of a harmful element to ruin your tank. i used tap water when i started my tank. i didnt have any problems. however i bought a RO/DI unit about a month later. i didnt even know what they where until i found this site. did it make a noticible difference? no. but i feel safe about the water now .

I agree. I wouldn't use tap water. Some things (like copper) may get in and stay in.
