ZEO weekly water changes?

[Mrfish55]

Does the salt really make that big a diff? I switched from IO a month ago to
H2O and in the last 4 weeks have lost two of my fav. SPS to RTN (10% water change per wk. on 300 gal system) I have been using Instant ocean for the past 18 years without issue and decided to try higher end mix figuring better results and am quite dissapointed. For the extra cash is it really worth it? I see tanks like Marie has and she has phenominal growth and color without the high end salts or the Zeo system.

I think it does. IO has basically nothing in it. You end up supplementing so much Ca, Mg and ALK that IMO its not worth it for anything other than a FOWLR tank.

But I mean, if you don't need it, don't bother...use IO if its working for you.
