I must be a sucky SW tank owner because I still havent managed to get my Nitrates down after months. Some advice I got on here told me to do larger PWC (40-50%) until they were down... After I did that twice (a week apart) everything in my tank started to die. So I was like agh- and took my water to a very good (well I thought it was) LFS and they told me now I was having ammonia problems too. So my ammonia was .5 and my nitrates were 60. So the guy said use ammo-lock. When I used that my mushrooms all detached from the rocks and 80% died, then my anemones closed up for like 2 weeks. When I called back another guy told me that what I was told to do was wrong and use reef solutions additive to help the bacteria and stuff in my tank come back and no water changes for a month. Well now my Nitrates are 80 and my ammonia keeps going to .5 and higher and I can't seem to stabilize anything. My fish are okay that have been in there, but any new fish I've added has died in 24-48hrs. On top of that I have this weird wormy thing taking over my tank (asked about this on previous post). So can anyone help? Or should I just give up?
