TheBrightwell Koralcolor is ok for lps and softies. But not sps. I've been dosing it for 5 months before I stop Didnt see no change in my sps. But my zoas did pop. I would not wast my money on it again I think I have 3/4 of it left. But VSV I started dosing it with mb7 and let me tell you that is the way to go for my tank. I did biofuel and Got hairalge. Thanks to sunnyx after seeing his tank inperson and his help. My tank did a 180 for the good.
With the vivid rainbow it's just one of those corals hard to keep it's coral. Very hard.
Thanks anyway Andy
for you newbies VSV is a mix of vodka+sugar+vinegar that I got from glassbox website.
