well it looks as though the bryopsis has withstood the kent treatment, bummer. Ive done a bit more research and discovered I have Bryopsis Penata wich according to some others is resistant to the treatment, wish I knew that before dropping ~$100 on Kent products. However I found a couple success storys using hypersalinity and suddenly a light bulb went off! My first tank, a 75 gallon, had the same algae bloom in its infancy. I was a noob then and didnt know the type of algae it was, untill now. I bought a sea hare for that tank and after a couple weeks the algae was %100 gone. I sold that sea hare to a man who e-mailed me the day after he bought it saying "Hey, FYI your salinity is at 1.030" (I use to calibrate my refracto with RODI water) I just put two and two together. It explaines where the bryopsis came from, I use rock from that setup in my current tank, and potentially how to rid the tank of this beast. SO, I have added to my arsenal and went out and picked up new bulbs for my T5, a sea hare, purple sea urchin, foxface rabbit fish (my heart is racing cuz after I put it in my tank, one of his eyes got cloudy and looks like a few ich spots), 10 varrious hermits and 10 trochus snails. The closed loop is now shut down for the sea hare and because last night I lost 2 more longspine cardinals. One to the CL and one got into my sump and sucked into my skimmer ARGH! Im praying that this works as im getting fed up with this vial plague. If this doesnt work its a toss up between starting over or Algae fix ect... Fingers crossed!
