Magensium chloride/sulfate ratio in 2 part solution

So long as you don't only use Mag Sulfate I really think you are just fine. If you just used Magnesium Chloride I think you would be fine as well.

Hmm, I think the ratio of chloride/sulfate is important in striving to achieve long term sucess. We try our best to match natural seawater and in doing so the particular quantity of these elements are critical. From what I understand, if magnesium is used to boost levels, or used with a calcium reactor, or Kalwasser (not in conjunction with 2 part additive) , then a ratio of 7:1 desire. If magnesium is used in conjunction with a 2 part additive (calcium chloride / sodium bicarbonate) then a ratio of 5:3 is desire. That is because in the 2 part additive, calcium chloride is already contributing much of the chloride, hence less chloride is required from the magnesium chloride/sulfate mix. I hope that makes sense. Correct me if I am wrong littlesilvermax, i just want to be certain before making the order.
