Hey folks, I was thinking yesterday it might be interesting to start a database of everyone's tank parameters and then try to perform astatistical analysis to see if we can identify which parameter or combination of parameter are most significant towards keeping health and happy corals. My basic thinking is that if we started a google doc that captures some basic information about everyone's tank, that information can then be dumped into a statistical analysis tool like JMP or minitab and we can start looking for trends or correlations. Obviously we keep some fairly complicated systems so capturing every nuance could be fairly complex but we could start with the big ticket items and then work from there. Off the top of my head I would think that things like Temperature (average), salinity, alkalinity, calcium, magnesium, nitrate, and phosphate, would all be included. These are parameters that most everyone at least look at once an a while and they have fixed values. For things that are a more difficult to quantify we can come up with a coding system to assign a value. For example the big question, would be that will help tee everything else up is, "Are you happy with the growth level of you coral" or " would you consider you coral to be healthy". For that we could code with 1 and -1. "1" being yes you are happy and "-1" meaning no I am not happy. We could also track tank age, dry rock vs live rock, sand vs bare bottom, so on and so forth. So who would be interested in participating? Please share you ideas for things you would like to see tracked. We have a very large number of active members on this site, if we could get a reasonable number of those to participate in this activity it could be possible to put together a large enough set of data to extract some useful information. Let's all work together better understand our oceans in a glass box.
