I live in Los Angeles and the TDS of Our Tap water is well over 456ppm.
After it has been through reverse osmosis DI, It is .04
If i dump straight tap into my SPS/LPS/Clam/and soft coral reef, I am sure everything would be dead over night, maybe a couple days.
I am sure some people have better tap water then me.
But for some of us, We need to filter our Water.
Thanks for sharing though...
