I'm sorry, I thought that after I did (the link). That was the site I used to use, and you are very correct that it is generic or "traditional". Ophiura, you know all about stars, and urchins? I am getting so frustraterd. I did the advice of everyone on this site, and raised the salinity to 1.025 with a two gallon bucket, over 5 hrs. my tank is a 55. My Urchin died two days later. My snail is still barely moving, moved 6 inches when I raised it, and he has been in the same spot since. I have 0 amonia, 0 nitrite, less than 40 nitrate, ph, 8.4 temp, 76 . Skimmer working well. what am I doing wrong?
