So, I'm ready to start my initial fill and my rodi is lost in the shipping world somewhere. Wondering if zero tds is really truly needed? my local walamart has ro water and its reading is 5. Wondering if that's safe or do I truly need rodi water with a zero reading?

5 is okay honestly. And once you get the ro/di unit and you start doing water changes, it will eventually get diluted out to 0, assuming your unit does indeed produce 0 tds water.
well I mean I sure hope it does! I just figured the Di is more for the benefit of the coral, I just wanted a second opinon more or less. Plus I figured even with a tds meter theres always a chance its missing a few ppm and who really knows if its ever really truly zero.
 

Gp!

Nobody can answer that for you since TDS doesn't tell you what it is, only that it is there. I hope it isn't uranium although glowing fish sounds fun
 

Do you quarantine new coral before adding it to your reef tank?
