I had a coral that is looking really bad. I have a 62 Gallon (Tall) Reef/Fish tank.
My tank has been set up for about 15 months
All fish look good and are eating fine
is at 8.4, Ammonia 0, Nitrite 0, Salinity is 1.025, but my Nitrate is 15ppm.
My I have an under tank sealife premier series filter with a protein skimmer. I did a 25 gallon water change about 2 weeks ago. All was good until this morning. I noticed that my colt coral was slumped over. I thought that it would stand up when the lights came on, but it did not.
I got home today and did a water test. Everything looked good except the Nitrate. I use a saltwater master liquid test kit. What could be making my nitrate spike and how can I fix it. I took the bio balls out of my filter about 8 months ago to prevent this.
I have some Seachem Prime which is supposed to remove Chlorine, Chloamine and ammonia and detoxify Nitrite and Nitrate. Should I put some in my tank?
The water I used for the water change was premixed and I got some fresh from the lfs
Can anyone help?????
