micro nutrients

At the image you see Heliopora in one of our experimental setups. Some reefers regard Heliopora as the ugliest coral they know. I guess this is because it will never become a colorful coral, it always stays dark brown. And albeit showing interesting growth shapes it will never move in the flow...

I did an ICP test, and I'm low in all of the elents found in both of these solutions. Any particular thoughts on using them in general? Any thoughts on which is better?
