I would like to add a succesful green star polyp story, I bought this softball piece of live rock at a lps at $10.00 perlb, will I took notice to the fact that it appeard there was a small colony of GSP that was doing very poorly on the rock, so I bought it for about $6.00 it was little over a 1/2lb, 2 weeks later sure enuff about 15 polyps appeared, today that rock is about 99% colonized, but the bad thing is my 75 is like 8 weeks old and I been doing a reef for about 6 months now, I started with a 20, I check nothing......lol I have no test kits at all and the more I read BB stories I start to wonder if I can handle this hobby, I mean like theres alk this, po4 that, ca, iron, trites and trates it gives me a headache thinking about it.....lol but my reef for now is doing just wonderful, looks great. I thought I would just add this for no good reason...
