If you are going to bump up your CH, buy this:
Snow Joe 20 lb. 94% Pure Calcium Chloride Ice Melt Pellets MELT20CPP - The Home Depot
Far, far cheaper than even the cheapest at a pool store. They deliver. You will need 30+ pounds of it, if really at 0 now, to get to 200 ppm.
Shop carefully - what looks to be Calcium Chloride "ice melt" may have a variety of additives (salt, Magnesium Chloride, etc.) that you don't want in your pool.
If you are after water feel, you may also consider adding salt to the pool. You should get the TFP recommended salt testing kit, but without a SWCG, you don't need to get all the way to the ~3000-4000 ppm they call for.
Mine's at 3200, and while I can sort of taste it, no one else that has used it can. But all who use it comment on the water feel. And I can float without an inner tube!
It won't change any of your other chem levels, nor will it hurt anything.
But...over time, the Cl additions also produce salt. So you may be highish already. And adding Cl will slowly move you higher. In which case you may have to do a partial drain to bring it down. A lot depends on how much make-up water you add during the year after backwashing/vacuuming to waste, and the amount of rain you get.
