I have an activated carbon reactor, will the reactor remove this stuff?

I don't know the answer but I shut my off for a few hours.

What distinguishes this from their regular calcium additive?

It's more than just calcium. It has all the elements of saltwater mixes. You use Reef Plus with this, and your saltwater tank gets the added vitamins and amino acids it needs to be healthy.

Seachem reef calcium. will it help strengthen the shell of my freshwater turtle? i have a reeve’s turtle/chinese pond turtle.

Made for saltwater! Need better foods for your turtle. Pond turtles don't need calcium supplements because it's usually in the water if you do water replacements!

My calcium (159) and magnesium (870) levels are low in my nano 13.5g saltwater tank. Will this boost both or do I also need a magnesium additive?

Water changes work better than anything in these smaller tanks. Is this a hard coral tank? I use Seachem Reef Complete and Reef Plus together. If its a coral tank and not a fish tank, then make sure your using a reef salt mix with those extra additives. You can also add Reef Rubble pieces to keep your levels up in between water changes. Smaller tanks need more water changes because things change quicker with less space.

Replenishes trace elements

Dislike the fact it replaces all elements as my aquarium is always high in calcium and magnesium.
