Does this provide a BALANCED supply of calcium, alkalinity and magnesium?
Yes, it should. It may not be exactly balanced but it shouldn't take much adjusting if things to get a little out of balance.
I agree it should be close. No method can be perfect for every tank, particularly with regard to magnesium since the consumption rate relative to calcium and alk will depend on how much coralline is growing (a bigger magnesium user) relative to some other corals (which can be lower). .
Thank you very much everyone, I realise it won’t be a perfect supply but I couldn’t see anywhere on the container where it stated that it had been supplemented with magnesium already.
It presumably has not been "added", but is naturally there. Aragonite (depending on the source) will have magnesium in it, just as corals depositing aragonite skeletons take up and deposit magnesium into the skeleton.
This is one of those occasions where advertising is not clear, it would be helpful if the containers stated the expected amounts of each element to be present per kilo or something.
Seachem do some great products but they also have a tendency to blur the truth of their products.
Again thank you
