Hi All, I have switch my phone to iphone I am not being able to find a reef calculating app. I like the Reef Chemestry calculater provided on marine depot since it has Brightwell Calcion (liquid, 150,000ppm), Seachem Reef Advantage Calcium (powder), Seachem Reef Builder (powder) and ESV 2 part, (I wish they had kalk but they don't) but its a pain to use a web app on a phone its just does not adjust to the phone screen so you have to scroll and guess Any advice would be highly appreciated Happy Reefing!!

For a while I was dosing Alk (ESV) at night to keep the pH swing a little more in check, usually about 8.0 to 8.1. I switched back to dosing throughout the day to maintain a constant alk throughout the day. The result of a continual dose over 24 hrs is a pH swing of 7.9 to 8.1. I'm curious what others are doing out there. Is anyone dosing Alk primarily at night to mitigate pH swing? Any thoughts on this? That said my SPS seem to be doing pretty well on the 24 hour dosing cycle. I'm not getting explosive growth but noticeable gains. Thanks for any input.

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 ?
