Only A of B?

Are there any issues with only using say the Alk part of a 2part system? My Ca doesn't need adjusting as often as my Alk, so can I just the Alk part of my Kents Liquid additives?

Should not be a problem.

That is OK (but not perfect).

Even with balanced consumption, calcium will "appear" to drop more slowly simply due to how much is present in seawater. But if you use a salt water mix with excessive claicum, so do not need as much calcium part, that is a fine plan.
