Hello everyone! I plan on setting up my first saltwater tank this upcoming weekend, but after doing hours if research, i'm still wondering what kind of water people use to rinse their biofoam and carbon. I'll be using a fluval AC50 HOB. Do i use RO/ distilled water or saltwater to rinse the media? And also which kind of water to fill the filter if it even matters. Maybe i'm overthinking it, but i just want to get the setup right
