This year I switched to a Hayward Pump and Sand filter and have been trying to keep it simple following the no-name bleach technique.

So far water is crystal clear but pool hasn't been used much and temps have been low.

So for a little insurance I had the water tested at the local pool shop. The problem is my chemistry knowlege is low and their terminolgy is a little different than most posts here:

Volume: 5280 US Gal.
Finish: Vinyl

Water Data:
Temp: 78
T.D.S. 300
Stabilizer: 40

Sanitizer:
Total 4.5
pH: 7.6
Acid: 0
T.A: 120
Adj. T.A: 120
C.H. 100

The suggested results are 2.23Kgs of BioGard Balance Pak 300 and also .2 litres of BioGard Banish.

Am I to assume the C.H. is Calcium Hardness and is this resolved with Baking Soda?

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).
