I have a 18,000 gal pool I'm opening. Can do the same thing ? Use stabilized chlorine , until I get to 30 on the CYA ?
Than once my CYA hits 30 ,switch to liquid chlorine .

You can use tabs/pucks or bags of stabilized shock to increase CYA, but it may be a bit too slow for you at first. When the CYA is below 30, the hot summer sun will tear-up your FC in no time. If it were me, I'd use granular stabilizer first to get at least to 30, then use the other products for a short period to increase to 40 if you want, or once in a while if needed to bump-up the CYA just a tad if it drops from splashout or backwashing.
