Thanks guys. The episode was clearly caused by the Vodka. All my parameters are stable and within the acceptable range . What started the bad idea is the constant nusicence algea I get will not disappear. I do a 50 gallon water change weekly with out fail, run a H&S nitrate reactor , Phosphate reactor with 500ml rowa , Deltec kalk stirred, fuge with live rock and Cheato and a BK 250SM skimmer. I have a mediumn/ high fish bioload and feed 2X per day. Dry in the morning and PE mysis in the evening. Nitrates are always 12 to 15 PPM and Phosphates are always .015. Desperate for a fix I tried the organic Carbon dosing approach and consider myself lucky to have only lost one fish and no apparent effect to my SPS. I do still have what appears to be a whitesh residue in my tank. It is most evident in my turbells. So I still remain searching for a method to export more nutriants then I bring in?? If you are interested my tank can be seen on fmas1955.org. I would appreicate further comments..
