I'm having some issues with invertebrates dying and after doing the standard water tests from a master kit and checking for stray voltage I am still stumped other than the idea of copper being in the water. I use our sink water (in New Brunswick) filtered through a 6 stage RO/DI and I usually use a mix of IO and Seachem Reef salt. Before I go get a copper test kit (which I know I should have) anyone know of any issues with NJ water?
