About to start testing a new salt. The recipe was designed to specifications which would suit a high end, demanding system dominated by acroporids and other more taxing corals. Have been asked to be tight lipped about any more details until I have tested it in my system.
Doing my first test this week, will keep you updated.
At the moment using Seachem Reefsalt, as it is the salt I have had the best success with in terms of colours and growth in my sps.
Ps. I see you have reef crystals as well as Instant ocean, please also add the other brands made by manufacturers, like Seachem Maine salt and Seachem reefsalt.
