I use the fauna marin amino acids daily..1ml per 25g, and I run the lith rocks in a TLF reactor...and it is dosed bak and bio daily...as for the trace I really like the ultra trace 1-4, now renamed for colors...so rather than ultra trace 1 that has a main component of potassium...it is now ultra trace blues...cause that is what colors will be most effected by that additive...so Fauna Marin ultimately has made the system even easier...and there are FAR less additives with IMO spectacular results than the Zeo..there are so many in the zeo line it gets to be just too much.
