Randy, I have a question. Since I've been using Epsom salts for the last couple years for my magnesium supplement do you think I should use a couple rounds of straight MgCl to offset the possible sulfate buildup? I do weekly 15% water changes religiously with maybe only 2-4 times of missing it due to vacation/sick. But also, I've been adding it to my IO waterchange as well at about 2 cups per week for my 32 gallon brute I mix in. That addition has been for about the last 4 or 5 months since I switched to IO from Coralife which had the mag already but other issues on ca, lith etc. which prompted the salt change.
