Well to make a long story short my OCD approach to Reef Keeping has led to a white X-mas (90% of my SPS has totally STN'd . In preparation of my departure for Thanksgiving I decided to tweak my maintenance schedule on my 150DD Reef in the garage. A little background on what led me to do this. My Vertex Alfa 200 had overflowed (Skim locker had been removed) due to me shutting down the return pump to do a water change. A few days later I notice negative effects on my SPS colonies! I performed a 35 gallon water change in addition to changing carbon, and RowaPhos. Note to self when changing carbon from one brand to another i.e. ESV to ZEO take it slow. You ask did I test my water first. Yes the results were as follows. Prior to departure. RODI: 00ppm Temp: 76.5 PH: 8.5 Alkalinity: 10 Calcium: 425 Nitrites: .0 Nitrates: <.02 Ammonia: 0 Phosphates: .0 Salinity: 1.025 Test results upon my return RODI: 00ppm Temp: 76.5 PH: 8.5 Alkalinity: 13.5 Calcium: 425 Nitrites: .0 Nitrates: 20 ppm ! Ammonia: 0 Phosphates: .0 Salinity: 1.025 My concern is what led to the swing in Nitrates so rapidly ? Could it have been the coral die off ? in addition to the rapid Alk swing which I would contribute to the lack of demand due to the decrease in healthy coral demand ? Well after all this I am considering on cutting back on the amount of tanks I am currently running and just concentrate on running the main display until we move back into our home. So look forward to a 150DD X-mas sell ?

Well i do not even know where to begin. It all started about a month or so ago. about a month before that i had kalk pour into my tank luckily nothing spiked and everything was fine and i siphoned out all the excess kalk and make sure to blow it off all my sps over and over again to make sure it wasnt settling on them. About a Month after that i started noticing STN on one of my monti caps that was previously growing as a weed. It began to turn white all around the edges and continued on until about 80% of it was completely white and dead. I then began to notice my SPS losing color turning brown and beginning to STN from the base up. I would frag them and glue em again even dip in iodine just to see. Still they continued to STN. I test my water at least twice a week with Salifert test kit. I always get 9 dkH for Alkalinity temp is at 77.5 steady. Calcium is at 500 Mg is at 1500 Nitrates showing 0 Phosphates show 0 Now i know both of those cant be 0 because i have hair algea growth and out of no where i had a cyano bloom. The tank has been up for over year. I run High Capacity GFO, I skim wet, do 20% water changes every 2 weeks. Have always used Kent Reef salt since the beginning of the tank and numbers have always tested the same. There are absolutel no pests in the tank myself and Decadence have looked over my SPS and everything else with a fine tooth comb and magnifying glass no Flaworms, no Red bugs, no nudibranchs nothing. Lights havent changed i run 2 D120 full spectrums. I run a 8 inch media back with Rox 8 Carbon and an 8in filter sock along with chaeto. I also vingear dose. I have tested for stray voltage i get nothing only .25v by my powerhead. I am seriously at a loss and cannot figure out what is going on. Its gotten so bad that i have Decadence holding some of my sps and they are coming back in his tank. I am about to build a stand and setup a 30gallon frag system just to house the SPS and get it out of the main display in the hopes this will help them heal why i try and figure out what is going on. Any help would be awsome as i am tapped out on ideas. everyone I have asked cannot figure it out. Decadence and I are at a loss. It sucks watching all of my once growing like crazy and crazy colorful sps waste away. Thanks guys! Justin
