calcium + water

are there any specific kinds of calcium to add to the water bowl that wont be too much or can it be any kind of calcium, im asking because i have 2 cleaned out pop caps full of calcium that sit in my tank and she never seems to bother them, i feed mealworms/superworms and dusting them does nothing haha it just doesnt stick to them

Theres no need for calcium in the water. Just leave the calcium dish (without D3) in the tank. Your leo knows when to consume the calcium when its needed. I've noticed it hard to dust mealworms, but you could try misting them with water before you dust.
