A lot of people are saying to go with regular IO and not the reef crystals. It will be a while before I actually have any SPS. Would it still be better to go with the reef crystals for LPS or possibly even coraline algae growth in your opinion?IO reef crystals, I guess since they came out with that version. SPS dominated. Can't go wrong!

I don’t understand how people keep NSW levels with IO.
If I used IO for my water changes (20% weekly) my alk would jump from 7.5 to 8.2 dKh. This is not acceptable to me.
I even adjust my aquavitro salinity from 9.5 down to 7.5 dKh with hydrochloride acid and aeration for a day....
