does anyone on Long Island NY use tap water and salt in their reef

[ChrisPPolys]

Don't bother looking at TDS to gauge anything about the usability of tap water. It is totally useless for that purpose. If they sent 0 ppm TDS RO/DI water to you, it would definitely be not OK to use by the time it got to you, dissolving copper pipes along the way.

I just looked up woonsocket in the other thread (page 4 of the link you show) and posted that 10% of homes have copper over 72 ppb. Not usable.

Got it, thank you very much for taking the time to check it out and get back to me.
