Water supply question

[musipilot]

A buddy of mine thats setting up a reef tank (125 gal) stated that he plans to use Poland Spring water to fill the tank. He gets it cheap. Any thoughts on this?

I'm not really familiar with the water. But if I was him I would have it tested for everything before using it.

Poland spring is good water, scrap that idea I did a 20G with bottled water and it was a pain in the #ss, Buy a RO/DI unit, or just an RO or DI unit not the bare bones thay suck. That tank is big.
