No.
Answer
My father used to do that; not terribly effective. You will end up with green water that needs to be replaced--more costly than getting the proper chemicals to begin with.
========================================
Actually, you can. Tens of thousands of PoolForum.com and TroubleFreePool.com users have been doing so, many for more than 10 years. And many, many thousands of pools in S. Florida are maintained with bleach by pool service guys.
Bleach is just a sodium hypochlorite solutions, like "HTH" is just a calcium hypochlorite powder. Both add chlorine to whatever water they are put in; but simply putting 'some' in will not guarantee good results.
Household bleach, typically 6% (check the bottle!), or commercial 'liquid chlorine', 10, 12, or 15%, can both be used. But if you aren't going to hire a service guy to do it for you, you should go to one of the two sites mentioned, to learn how. PoolSpaForum.com, Havuz.org and Gardenweb sometimes have posters advocate bleach use, or the BBB Method, but it's not consistent at those sites.
For obvious reasons, pool store employees don't think that grocery store bleach is a good idea!

Re last paragraph. I write as a user not pool store employee, but still trust the latter not someone trying to use cheap-skate methods like household bleach. In fact it would work out more expensive because it is sold in small quantities already highly diluted in water. It could also contain additives like perfumes and surfactants.
Further, if you buy stabilised swimming-pool disinfectant (Trichlor, troclosene, etc) for the maintenance dose, you won't need to worry about calculating and adding isocyanuric acid separately. Though you will need to monitor stabiliser level because in time it accumulates and "locks" the chlorine so it won't work.
Use the proper stuff! A swimming-pool is a costly item so why use spuriously-cheaper work-arounds to look after it? Those "pool service guys" may be using "bleach" but I bet it's actually a very strong solution of pure calcium hypochlorite or trichlor. They won't use just household bleach if they are reputable contractors. Same active ingredient but much purer and much more concentrated.
Green colour in the water is probably algae, which seems to be more tolerant of the disinfectant than bacteria are. You can buy proper pool algaecides to keep this at bay. The one I know is capper sulphate sold in a strong solution. On contact with the water it creates an alarming greyish-green cloud but that soon disperses.
Chlorine is bleach and it could bleach out your clothes if concentration is high.
Yes.
Health laws in the U.S. require a certain percentage of chlorine in a swimming pool in order for it to be healthy for humans to swim in. Does YOUR bleach have chlorine in it? Public drinking water supplies have small amounts of chlorine and fluorine in them.
sure...but be careful of your pool colors fading...hehe additional notes: you can use laundry chlorine in a pool. The concentration is generally much weaker than the chlorine you can purchase intended for swimming pools, so you may need to use much more of it to get the cleaning/sanitizing effect you are looking for. Any bleach with additives that would not be recommended for a pool would not be ideal. If you are in a pinch, it would be okay to utilize this product.
in chlorine bleach it is.
bleach
Bleach is unstabilized chlorine. It is just a weaker form of the chlorine you buy at the pool store.
I do. Use half as much. Pool chlorine is 12.5% sodium hypochlorite Laundry bleach that I use is 6% sodium hypochlorite. Sometimes I dilute the pool chlorine by one part water to one part pool chlorine and use it just like regular laundry bleach.
Yes, bleach is Sodium Hypochlorite, or commonly referred to as liquid chlorine in the pool business.
They use some kind of chlorine bleach to disinfect the dirty pool water.
Chlorine is bleach and it could bleach out your clothes if concentration is high.
Yes.
NO! There are often stabilizers in pool chlorine tablets that make the tablets last longer - use a bottle of bleach (sodium hypochlorite) instead.
Yes but you also need chlorine stabilizer (CYA) or the chlorine will be destroyed by sunlight in a very short time or you need to add the bleach in doses thoughout the day to maintain the chlorine level. Bleach is the same as liquid pool chlorine but at a lower concentration.
sock it with chlorine, bleach
Standard laundry bleach works fine in a pool. You should be sure to get plain bleach, not scented. The chemical in bleach is exactly the same as the chemical in pool chlorine but is generally about half the concentration. Most bleach is 6% sodium hypochlorite while chlorine for pools is 10-12%. So generally you would use about twice as much bleach as chlorine. The amount you add must be determined using a test kit to determine your current level of chlorine. An online calculator to use to determine the amount of bleach to add is at http://www.poolcalculator.com. As an example, if you have 0 ppm chlorine now and want to raise it to 4 ppm in a 23000 gallon pool, you would need to add 196 ounces (about 1-1/2 gallons) of bleach. For more help maintaining your pool using standard products like bleach, baking soda, and borax, search on "bbb method."
Chlorine is used to disinfect swimming pools and control algae. Don't use household bleach for this - it's not nearly strong enough. Get chlorine that's made for use in pools. The chlorine will be ineffective unless the pH is within the correct range.
