Either way is fine - whether you add cya directly and then just use bleach or if you use trichlor pucks for awhile to build up your cya and then switch to bleach. Both will work. Personally, I just add cya and then use only bleach. Some others use the pucks until their cya starts to get too high and then switch. Really just a matter of preference. If you do use trichlor, you'll have to test cya periodically because it will continue to rise. But, you'll be killing two birds with one stone - adding cya and chlorine at the same time. On the other hand, if you just add the cya outright, you'll only have to test it a couple of times until you get it where you want and then the level should stay put for the summer. Your choice.
If you do decide to just add cya separately, add enough per label directions to take your cya to about 30ppm. Add it directly to the skimmer. Then wait about a week to give it time to dissolve in your filter and don't backwash during this time. Be patient. If you don't give it enough time to dissolve completely, you may end up adding more than you should. Then you have another problem because the only way to lower cya is to do a partial drain. Better to aim a little low initially and then sneak up on the desired level of 30-40 than overshoot it. Hope this helps.

I occasionally use pucks--when both my pH is high and I want to raise my CYA level slowly. Or I'll use up some of my di-chlor powder. When both are gone, I'm back to my mainstays anyway, bleach, CYA, dry acid or muriatic acid.
IF you test your water everyday for chlorine and pH, and check all the tests once a week (FC, CC, pH, T/A and CYA) then you can control it. Sooner or later using pucks your CYA will hit the max you should be using (it's different for each situation and owner's preference).
The key to EVERYTHING in pool maintenance is proper, frequent, concistent testing. Takes 2 minutes a day to run the OTO kit chlorine and pH test. Even with Ben's kit and the FAS DPD powder it only takes 5 minutes a day to test chlorine and pH. The full battery of tests takes about 15 minutes, once a week. It will save you are WORLD of trouble and a heap of money.
