How would you get rid of green alge in a swimming pool?

Answer 1

Foamy pool There are two main types of algaecide: metallic (copper and silver) and quaternary ammonia. Both types are effective, but ammonia tends to be used more often because it's both less expensive than metallic algaecide and not as likely to stain the pool. The only problem with it is that it tends to suds up, which some people find annoying. I think that just running your filter 24 hours a day for a few days will get rid of the foam. Again, failure to READ THE INSTRUCTIONS ON THE PRODUCT!!!!!!!!!!! but if you're in a hurry use a half a gallon of cascade dish detergent per 10,000 and run the filter for a couple of hours and the foam will be gone

Answer 2

biocide

Algae is fairly easily killed by shocking the pool with a chlorine product such as dichlor or cal hypo. Generally, you will find that you will need at least 10 times the ppm of chlorine currently in the pool. I have had a pool so bad that it took shocking twice a week for 3 weeks to totally get rid of the algae. About 2-3 days after you shock, retest the water for ppm chlorine. If the chlorine is all gone, and you still have live algae, you will need to reshock. This needs to be repeated until the water holds at least 5 ppm of chlorine 2-3 days after shocking. Then you will need to vacuum excess dead algae out of the pool and thoroughly clean your filter cartridges. At this point, you can use a maintenance dose of algaecide to help prevent a future outbreak. I prefer a silver based or quat based algaecide. Copper based algaecide can turn blond hair green.

Make sure during the summer that you always have a 2-4 ppm chlorine in your pool. If you have a heavy bather load, you may use up all the chlorine, which allows the green algae to sneak back in.

Answer 3

check to make sure your p. h. is 7.6, than shock water with chlorine shock from your pool store, run pool for 24 hours and brush and vacuum.
