TDS is almost irrelevant. It has some secondary effect, but really can be ignored.
The worst thing to do is to add calcium and then add something that raises the PH not very long afterwards. That includes bleach, liquid chlorine, soda ash, borax, cal-hypo, baking soda, lye, etc. High PH is the primary cause of calcium clouding (and also high CSI). While the chemical is being added there will be local areas with much higher PH, until the chemical fully mixes in. Calcium clouding can develop in those high PH areas, and then stick around afterwards.
Many people say to give a full 24 hours between adding calcium and anything that raises PH. I don't think you really need to wait that long, but give it a good while.
Lowering PH is a good way to get rid of calcium clouding, so no harm adding calcium and lowering PH at more or less the same time. If you are lowering PH and adding calcium, it is safer to lower PH first, but it won't usually make any difference.
Calcium clouding will almost always go away reasonably quickly if you can get the CSI to be negative.
