Fuel? Ions? Calcification?

[BrandonM]

Is there an all in one additive for saltwater tanks? This may sound like a dumb question but I don't want to buy things i dont need ... Any input helps. Thanks

The only true all in on additive per se is a water change.

The most commonly used additives would be calcium, alkalinity, and magnesium although many other things are dosed regularly by many reefers. Like aminos, trace elements and carbon sources.
