Well, not exactly sure what "minerals" means, seems almost like the salt range to me. The mineral springs stuff is more snake oil.
Balance pak 100 = expensive baking soda
Balance pak 200 = soda ash
Looks like you need some of the balance pak 100 because your Alk is low. However, you can do the exact same thing with baking soda, bought in bulk for cheaper. Sams/Costco/etc have 12# bags of baking soda for this very purpose.
I wouldn't use the Balance Pak 200 for your pH, as soda ash has a nasty habit of making your Alk rise. Most folks here use Borax to adjust pH upwards. It's cheap, and availible at your grocery store in the washing soap aisle. Hard to tell how much you need, because your pH wasn't posted.
You are missing results for: pH, Ca, CYA, pool size and pool type (vinyl liner? gunite/marcite?) Get those results and we can help further.
