just read on another recent thread where Randy has said it is not clear what the detrimental effect of elevated sulfates are in aquaria, if any. having said that, he said he recommends magnesium chloride over magnesium sulfate, but better to combine the two in correct ratios per his recipe.

i'm assuming that this recommendation of the magnesium chloride over magnesium sulfate is due to the fact that the excess sulfate builds up more substantially (relatively speaking) when using magnesium sulfate than the excess chloride does when using magnesium chloride.

having said that, it seems like you can reduce the detrimental effects with water changes.

i guess the way i look at it, if i'm going to be ionically imbalanced anyway, i might as well not be paying seachem to make me that way!
