Chlorine - you can buy "pool shock" at Walmart, pool specialty stores, or maybe even Menards. After a couple days of "shocking" a pool, though, any algae with die and turn brown, meaning you'll probably have to scrub the walls and floors of your liner and filter out the dead stuff.
Also, my understanding is that bleach does have the same effect.
Depending on your pool size, I'd say you should use at least 1/2 a gallon of one of these solutions every day, pouring it around the perimeter. Like I said, after a couple days the pool will become brown. If you have an inflatable pool, use much less; you'll probably have to use more bleach than chlorine/shock.
To prevent algae from growing and to kill bacteria
It is often used in pools to kill both algae and bacteria that is produced.
Salt water pools are chlorine pools it just that the chlorine is electronically made from the salt. Salt water pools have problems with algae the same as just freshwater chlorine pools. If you are lucky you may be able to nip algae in the but by over chlorinating but more often then not you would be well advised to throw some algaecide in the pool to kill it of. (Always follow the directions on the bottle.)
Chlorine is always a must. You can also get algae killer/preventer and also make sure you have a working clean filter.
You can buy pool chlorinating chemicals that prevent the growth of algae and bacteria. You also skim floating debris off the top, and vacuum debris off the bottom. (Outdoor pools tend to get lots of debris; indoor pools get much less.)
Yes. Chlorine is used to prevent the growth of algae. Some pools use salt.
Chlorine, because of it's pH level. Some pools use salt, but Cl is most common. Home pool owners may occasionally just dump household bleach into their pools to "shock" it. This kills culturing algae and other lichens
You can buy algae control chemicals, but it will kill your snails if you have any. I use a scrub brush with a texture of SOS pads, but it's plastic so it wont scratch the glass.
Answer: Perhaps you have an algae problem.
No, algae is not a problem in a desert. It only appears for a short time in pools that form after summer rains.
Algae is a water purifier and will not kill Guppies at all.
Hey, In most pools it is chlorine, but newer pools have been known to be use different chemicals.
