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 ?

Hi Gang.. so, yesterday I went to the LFS and got some H2O and then topped off the tank with Fresh H2O last night in preparation for a water change today. I changed the H2O with Salt water from the LFS about 5 hours ago… temperature is back to normal, but the PH had dropped DRASTICALLY! OMG… Not quite sure what to do about this.. I have a 36 Gal Bow in the basement, 2 clowns, 2 shrimps, an Urchin, an anemeomeoemeomeomeeeee 3 green chromes and a flame angel. And as you can see in the screen shot below, prior to water change, the PH was actually riding a little high @ 8.5. Any ideas? help help help! Don't need my fish swimming around in acid! <----- click photo to enlarge! -B

Has anyone here built a DIY CO2 scrubber to plumb in-line to their skimmer intake? What materials did you use to build the container? Where did you get your soda lime? Did you have any issues/pH spikes?
