SG 1.025

Using ELOS and Salifert for Ca, ELOS for Mg, Salifert for Alk.

There are thousands upon thousands of home reefs that use IO including my own despite it being a bit low on Ca and sometimes Mg. I may try another salt one day, but IO is usually the cheapest and the most plentiful.

IO for 6 years. I get incredible growth.

I supplement my salt with some magnesium and calcium, costs about $4 per pail.
