Heck, if the pool goes un-chlorinated for 2 days you're gonna have the start of a swamp! It's gonna be a real pain to have to be adding bleach several times a day so why don't you go ahead and throw in some stabilizer? In a 12K gallon pool, you'll need about 4 lbs to get to a CYA level of 45-50. Get an old athletic sock and put some in it and hang it in front of a return jet. If you give the sock a squeeze once in awhile it will help it dissolve faster. I doubt the sock will hold 4 lbs. so you'll probably have to do it in a couple of doses. When you buy it, it may be labeled as stabilizer or conditioner. If the ingredients are cyanuric or isocyanuric acid, that's the right stuff. Once the CYA is in there, you'll need to keep your chlorine between 3-6 instead of 1-3 but it will allow you to not have to add bleach multiple times per day. You should be able to go to testing and dosing in the evenings only.

Once your SWCG is up and running, you'll probably need to add additional CYA. Check your manual. Most SWCGs need 60-80ppm of CYA.
