Honestly, if you could determine exactly what element is a little off, it's truly worth it. Growth rates with that stuff really is insane.. I cannot lie.. But at the same time, some things we just cannot get to work with our individual systems..
I loved it in my last tank,I truly did.. I am only experimenting because of the Alk being high and causing, what I think is burns on my few frags I have. It has been a hard decision to break away from it, because you do get the growth and great color(if you think at the beginning the color or growth is good, just give that stuff some time).. And you don't have to dose a ton.
I am one, if I see some improvement,I will tinker for a little.. It may be one thing.. And yes, any kind of algea is a turn off, so I feel your pain.. But the one thing I did do after switching and have done ever since, is use silica absorption in my ro/di.. I can't remember why.. But I know it was around that time that I did..
