Whats the best way to clear up a pool that is starting to turn green?

Answer 1

Green algae is a common swimming pool problem, which may appear as a greenish growth on the floor and walls of a swimming pool, a green tint to the pool water, or greenish material suspended in the pool water. The only swimming pool chemical that will kill an algae growth is chlorine based swimming pool “shock”. Shock is a granular form of highly concentrated chlorine, which quickly raises the chlorine level of the swimming pool water. The elevated chlorine level makes the pool water conditions unlivable for anything organic, and algae quickly dies.

Before adding a dose of chlorine pool shock, the pool walls and floor should be brushed to remove as much of the algae as possible. This will greatly reduce the amount of time it takes to kill and clear the algae bloom. The normal “maintenance” dosage of most swimming pool shock is 1 lb. per 10,000 gallons. This dosage should be increased to 1 lb. per 7,500 gallons, or you should follow the manufacturer’s dosage suggestion for killing algae. Chlorine pool shock needs to be dissolved in a large bucket of water before it is added to the swimming pool. Always add chemicals to water when dissolving. NEVER add water to chemicals. The swimming pool cannot be used until the algae is dead, and the chlorine level of the pool water has returned to the safe range of 1-3 ppm.

The pool filter system should be running when the chlorine pool shock is added, and the filter system should continue to run 24 hours a day until all signs of algae have completely left the pool. Monitor your pool filter system closely and thoroughly backwash or clean the filter each time the pressure rises 10 psi. above the normal operating pressure. The dead algae that your pool filter collects may quickly dirty the filter, and need to be cleaned out frequently. If the conditions of the swimming pool does not significantly improve after 12-24 hours of filtering, add a second dose of chlorine pool shock at the increased rate. Once the algae is dead it will turn a white or grayish color, and it will be suspended in the pool water or settle to the floor. When there is no longer any sign of the color green in your pool, thoroughly vacuum the swimming pool. The pool filter should be backwashed or cleaned to be sure that dead algae is not trapped inside the filter. If the filter is not thoroughly cleaned the algae may quickly return.

Test and balance all of the pool chemical levels using the guidelines below, and pay particular attention to the chlorine level of your swimming pool water in the future. Algae and harmful bacteria are almost immediately destroyed by a chlorine level of 1 ppm or higher. You have experienced an algae problem because you have not properly maintained the chlorine level of your swimming pool, and it was allowed to drop below 1 ppm. Test pool water frequently and make any necessary adjustments for a clean, safe and easy to maintain swimming pool.

Answer 2

It needs to be "shocked". You can use bleach or "shock" which is concentrated bleach chemical from a pool supply. Depending upon the size, start out with two gallons of bleach, let it sit overnight and start up the filter. You may have to do this a few times to get it cleared up. You need to stay on top of keeping it clear by shocking it at least once a month. The warm weather plays havoc on a pool and you can have a lot of algae from it. Just make sure your filter is running properly.

The BEST WAY???
Take a sample of your water to your local pool store and have them test it and tell you what you need!
(even then its usually a tedious task)

Not many people (if any) can literally trouble shoot YOUR pool water to the point of suggesting do 1 2 n 3 and that will FIX it.

They don't know if you're in a lot of shade, how much traffic you've had, what kind of body chemicals have been in your water such as make up, cologne, lotions, and other unseen chemicals.

I say THE BEST WAY is take it in and have it tested!

Answer 4

Clean out your filter. Brush the pool down. Add shock. Let it filter for at least 12 hours. Add chlorine in powder form (shock is a strong form of chlorine) according to the amount of water in your pool about once/week. Don't swim in your pool for several hours after adding the chemicals.

Answer 5

Get a water test done to know where your water chemistry is at this point. Specifically you want readings for free chlorine, combined chlorine, total chlorine, pH, alkalinity, hardness, cyanuric acid, metals, nitrites/nitrates, and phosphates. You will probably have to take a sample down to the pool store to get it tested for all of these.

Two things will help algae bloom even in a properly chlorinated pool... nitrite/nitrate and phosphates. Removing these two compounds is essential when battling an algae bloom.

Additional chlorine is needed and it can take quite a bit to do it depending on the severity of the bloom.

Answer 6

Algea is growing. Youll need chemicals for your pool to clear it up. Go to a store that sells pool supplies and they will be able to tell you the best things to use.

Answer 7

10 litres of liquid chlorine to "shock" treat the algae
run the filter overnight - take a sample of the water to a poolshop - you may need additional chemicals

Elaine is right

Answer 8

drain it and start to strub . i know this sounds like a lot of work, but we did this every year when i was in school. when refilling make sure filter system is working and balance chemicals according to directions
good luck

Answer 9

Bleach will clear it up fast.

Answer 10

you have to go get a vacuum and cleaner and clean it or get someone to clean it 4 u
