Saturday we upgraded from a 75 gal to a used 210 w a 75 gal sump. We (the lfs that we hired) did a direct swap using the sand from the original tank and the used tank (it was set up and running at the guy's house) and the water from my tank. I tested water morning and evening but didn't test Thursday because it was always within normal perimeters. I tested today when I got home and my nitrates are literally off the chart. I had 20 gal of water made up and I changed that much immediately but with such a big tank it really didn't affect it. I'm currently making more water but it is a slow process and I'm a little freaked out. My tap water tests ok with phosphates at 5. Should I use tap water just in this instance to get enough water to get my nitrates on down?
