You should lower your pH to around 7.7. If you don't get it done today, do it in the next couple of days at most.
I would suggest you not use the pucks. You will not get CYA as fast as you need it (Why did you just put in 4 lbs...are you using PoolMath to calculate your dosage?) You can save your pucks for later....they don't go bad.
