Some reefers boost Ca with one or the other, or both. Which one is better/easyier for corals to use for growth?
calcium chloride or calcium hydroxide

Calcium chloride is useful for boosting calcium only, or used with other materials like baking soda in my DIY two part.
Calcium hydroxide is used to make limewater, and boost calcium and alkalinity in an appropriate ratio to balance calcification by corals.

Ok, but the actual calcium in each substance is the same right?
Yes, the calcium is exactly the same, although there is more on a weight basis in calcium hydroxide than in calcium chloride.
