I'm losing about one fish per 1-2 days and I'm not really sure why. It's quite frustrating. I'm thinking it's high nitrates but I'd like to get some advice. Ammonia = 0, Nitrite = 0, Nitrate = ~50-60. Temperature between 80-82, pH at 7.2. I have a good amount of plants and I dose excel every day and comprehensive twice a week. I've got 8 neons left, 5 panda cory's, 1 bristlenose, 2 rams, 4 amano shrimp and 4 red cherry shrimp. My tap water has a Nitrate level of about 80 so doing a water change makes it worse. I bought one of those nitrasorb pads and put it in my sump yesterday, we'll see if that helps at all.
I treated for ich about 2.5 weeks ago by slowly raising the salinity for about 9 days. It cured the ich. I think I did too abrupt of a water change and decreased the salinity too fast because a few fish developed "popped eyes". I only changed about 50% of the tank water though. I haven't done a water change since that 50% water change (about 9 days ago).
Any advice for me? I'm trying to order a few more fish and a bunch more shrimp and I'd like to get this problem resolved before that.
