Useless number pool stores like to make sound impressive.

Bang smack in the middle of the suggested range of 30-50.
Sanitizer:
Total 4.5
This is chlorine. 4.5 is fine for a maintenance level, so long as Free Chlorine (FC) also equals 4.5 and Combined Chloraimines (CC) = 0. That assumes a CYA level of 60 or below.
pH: 7.6
Perfect!
Acid: 0
I have NO idea what this is. Is this acid demand (useless test) or Cyanuric Acid (Stabilizer--very important)? It can't be CYA--that you said is 40ppm.
T.A: 120
Adj. T.A: 120
Perfect again.
C.H. 100
This is calcium and is irrelevant for a vinyl pool. Anything from 0-500 is OK. Above that causes cloudy water or scaling.
The suggested results are 2.23Kgs of BioGard Balance Pak 300 and also .2 litres of BioGard Banish.
Naturally! They HAVE to suggest SOMETHING! Bal Pak 300 increase calcium. You absolutely do NOT need it. Do not buy it or use it! Banish is an algaecide, but NOT Polyquat. Absolutely do NOT use this either! Both these products AT BEST are useless, and are more likely to cause you problems!
Am I to assume the C.H. is Calcium Hardness and is this resolved with Baking Soda?
Yes to the first, no to the second. You have NOTHING to resolve. 100ppm is FINE for a vinyl pool. Don't worry about it at all! Baking Soda raises total alkalinity.
Thank you for your help as hopefully this will be my last season a true "Pool Newbie". Within a year or 2 I'll be ready for a big pool, (and so will my kids).
