Hi and welcome to the Pool Forum. Your pool's volume would be around 12,000 gallons. Each quart of 6% bleach would add approximately 1.2ppm of chlorine to the pool. But, without knowing what your current water testing results are (taken with a drops-based kit -- no "guess strips"), we cannot advise you what chlorine levels you need to run.
If you don't have a good kit, you should get one. The one we recommend is the Taylor K-2006 or 2006C which you can get through the testkit link in my signature.
In the meantime, you should pick up a cheap OTO/Phenol Red kit (red and yellow drops) at Walmart or someplace. If they have the HTH 6-Way kit, that is also a good starting kit to have before you get your good one.
In addition to chlorine and pH readings, the CYA reading is also important to know since your needed chlorine levels are based on the CYA. (See the Best Guess Chlorine Chart in my signature.)
Repost with some numbers and also tell us what size pump you have and if you have a kit of some sort. What condition is the water in?
We'll help you get going with this once we have more info. Hope this helps.
By the way, do a lot of reading here on the forum (especially the stickies at the top of each forum.) Also read on our sister website www.poolsolutions.com.
