Managing how much bleach you need to add to maintain the appropriate FC level in your pool is known as chlorine demand. This is dependent on several factors including the # of gallons of water in your pool, the strength % of your bleach, the CYA level, amount of sunlight your pool gets each day, water temperature, bather load, and how diligent you are in keeping the pool free from debris (skimming leaves out, vacuuming, etc.). You will get a feel for your pool's normal chlorine demand with experience. Even after you get a feel for that, you will need to make occasional adjustments for events like pool parties, heavy rain (can introduce organic matter into the pool), etc. All other things held constant, chlorine demand tends to drop as water temperature drops and rises as water temperature increases.

BTW, what is the "pool conditioner" you are adding? Is that the CYA (stabilizer) or something else?
