I use normal IO the purple one, would it be any difference going to Red Sea blue bucket? I just keep leathers and softies. I just use the IO because of price, but I would pay a little more if I would notice a difference.
Only real difference would be the parameters, Alk/Cal/Mag mostly. IO is said to be more “dirty” when mixed, but I, along with many, use the IO reef crystals and I have no issues with that. Since you don’t keep SPS then you shouldn’t have the need. Save that extra dough for more zoas!
You would not notice the difference.
Salt is salt.
It’s you that makes the difference.
Keep your $
Some of the best tanks I’ve ever seen use IO.
Stick with what had worked.
