I have an above ground pool. Can I use household bleach to kill algae? My pool is overrun with green algae. Thanks.

No on chlorine bleach! It's not healthy for humans or the environment! Go to your local pool supply company and ask them what products you need to get rid of the algae and what products for maintenance thereafter. They also carry long poles with special pads on them that you run along the bottom and side pool surfaces that help loosen the algae and should also be used for regular maintenance.
Never mess around with chemicals, unless your pool dealer has them in stock. The first step is to bring a sample of your water to determine the right course to clean up the algae, or other problem you may have. Otherwise you are making a possible toxic soup which may harm humans, or destroy the pool. Trying to save a few dollars may cost bigger bucks in the end. I have a friend whose well meaning, but clueless husband "dumped" every product they had bough for the pool, all at once! He figured this would keep the pool clean while they went on vacation. Upon returning home the pool was like a bubble bath, and not usable for several weeks after. Then an algae problem developed and that was the end of the pool season. I check my water every other day, and if something needs to be added I do it then. Always read the instructions as to the amount and how to use it etc. Good luck to you!

We have a very large above ground swimming pool. Does anyone know how to get them clean after algae has gotten in? We have used Shock It and chlorine and clarifier. Still green. Thanks.
We have a smaller blow-up style pool that is about 3 1/2 ft deep and when we first got it we never had a problem. It was in our yard on some sand. The kids kept getting sand in the pool so we moved it to a grassy area and now it gets algae.
Last week I added about 1-2 c. bleach and have not had any trouble since. (07/13/2004)
There is something that is used to control algae in ponds called "Blue Stone". We have used this in our pool for years. We buy it at our local feed and seed store. It is very cheap and is sold by the pound. (07/13/2004)
We had green algae in our pool this summer. It is real easy to treat. Use your pool brush to brush off any visible algae. Then double shock your pool. Treat with super algaecide. We have not had this problem since treating it. (07/20/2004)
Try pool algaecide. You can get it at Bi-Mart or Fred Meyers. (05/29/2005)
We used a Bioguard product called Erase. It worked wonders when all else failed. Take a water sample to be tested and see if you can find a Bioguard dealer. (07/28/2005)
I didn't find this product to be very effective at all in the dosage that is recommended. I have had same problems with green algae in above ground pool. Had water tested and was told to use *buffer* then add extra chlorine to what is recommended. Then to add extra chlorine on a regular basis. Problem has been somewhat fixed. Hope this helps a little. It was a pool dealer place in Qld that recommended this to me. (02/22/2006)
Types of algae
Algae in swimming pools is referred to by it color.
Preventing pool algae:
Maintaining proper water balance and minimum sanitizer levels will ensure that any algae spores entering the pool water cannot take hold. Most pools use chlorine, which should be kept at a minimum level of 1.0ppm. Using the Pool Wizard or any similar mineral system may allow you to keep the free chlorine level at 0.5ppm without the risk of developing an algae problem.
Destroying pool algae:
Once algae has been allowed to bloom, it is quite tiresome to destroy. The common steps to get rid of an algae problem are:
The Pool Wizard and pool algae problems:
The Pool Wizard was developed to destroy algae and bacteria, and prevent their reoccurrence in swimming pool water. The 24/7 protection the minerals claim to provide may help prevent algae and bacteria from multiplying in pool water even when chlorine levels hit zero for a couple of days. With the Pool Wizard, algae may become something you find in that health supplement you take every morning, not something you see in your pool. (08/26/2006)

Green in pools that refuses to go away:
Pink Algae - It is the worst, it forms a shell over itself. You have to brush it each time with a hard bristle brush and hit it with PH Minus to kill it after brushing.
Every year when I open I have this problem. Usually I put in four times the maintenance dose of Algaecide and three times the shock amount. After three of these treatments on successive days I usually get control back of the water. Back flush frequently and vacuum the dead algae. I have a Polaris robot and it puts the dead algae back in suspension where the filter can remove it. I use a clarifier which helps to clump the algae so that the filter can take it out.
I have not done it since copper sulphate is a poison, but the most effective algaecide is nothing but a very dilute copper sulphate solution. You buy this at a tractor supply or a farm co-op, usually in 25 lb bags. Landscapers also carry it to keep algae out of ponds and fountains. You could put a small amount in a sock and suspend it in the pool. I would check the mixture concentration in the algaecide and mix my own as well. (09/07/2008)
