KH below 6 is not allowed. First, ignore the schedule... Raise Ca (with calcium chloride) to 410, while measuring KH every day and maintaining it at 7-8 (with soda) until it levels out. If calcium reaches 500, keep KH at 7-9 with soda; of course, during this time, calcium chloride is not needed until calcium drops to 410. After that, use both... With the current Reef Salts containing elevated calcium levels, it takes about 2-3 months to lower calcium, unless you are growing hard corals. Clarify if needed—I will respond.
