There really is an "easy" answer to this question. If it is just a tint of green, shock your pool and run the filter for 24 hours. You are starting to get an algae buildup. Go to your pool store and get some chemical to add to the water to prevent algae. I had the same problem two years ago. Since then I have treated the water every week with PhosFree. This is what the algae feeds on. It works when used regularly. Catch the growth NOW. Algae spreads very fast!!!!

Water clarity depends on three things.

1/ Proper water chemistry: Ph 7.2 -7.6, Cl 1.5 -3.0 and Ta 80-120. If one of these is off, your pool will go green or cloudy. Fix it and there's no issue. You don't mention what your readings are nor pool volume so I can't help there.
2/ Filtration: Clean the filter at least on a weekly basis, more often when you get into an issue that you have now.
3? Keep the pool itself clean. Vac it. Stuff lying on the bottom eats up your chlorine reserves in the water. It costs you money.
That's it in a nutshell. It's easy to keep a pool crystal with a little attention in the week. You let it slide just one day and .it costs you money to fix and time. Get your chemistry dealt with now, before you cover. Once it's good go ahead and close the pool. The chemicals you toss in from a typical winterizing kit will keep the pool pristine all winter as long as your cover stays on. I'm no pool expert but i would think a pump and chlorine would fix that alternately you can drain it and clean it every few weeks. All you have to do is make sure when you cover it in the winter that it covers securly and also I had an above ground pool and it had a filter if yours doesn't then maybe buy one or get a new pool that does and I wish you the best of luck Chlorine is the fix. Vacuum first and then purchase shock. Its a chlorine treatment for the pool. sounds like you may have algea growing in there. I would drain it & clean the liner or possibly using chlorine may get rid of it. you will have to drain it and clean it, put plenty of chemicals in the water, there is no guarantee that it won't turn green, but, you are going to have to clean it before next year anyway. Keep it completely covered. Otherwise have you considered salt water in the pool, far less maintenance and generally easier to stay clean. Our pool always goes green if it hasnt been covered up. Also if it is green and you do swim in it, the water soon clears up. Try it. You've got algae. Get some algicide as quick as you can off the internet ( in the UK is good if you are from the UK!). You need loads though, more than you think. Then overwinter as usual. I hope this helps xx clean that mother f*$ker up First purchase a chlorine testing kit and some algecide. You can probably get both really cheap at a pool and spa store.

1. Backwash your filter (depending on the type of filter you have, you may need to add diatomasious earth, a white powder)

2. Use the testing kit to check your chlorine and PH levels. Make sure you keep the water at the appropriate level.

3. Read the directions on the algecide bottle and add the appropriate ammount.

Run you filter for 48 hours and your water should clear up. If it doesn't completly clear up (or if it is reallly Green) vaccum the pool after the 48 hours and add more algecide. empty it now and leave it like that through the winter but give it a good clean before covering down First depending on size clean pool with vac .15000 Gal pool will require 2 1/8 pounds of shock or about 18 oz. You use chlorine tablets large put about 4 into the skimmer. Never put chemicals into bottom of pool .Will damage liner or discolor.Run pump for several days .Water should start to clear. You can add a couple of chlorine tablet few day later if water still cloudy. After clearing water go get a winter kit they cost about 20 to 30 dollars. follow directions . you should be OK and then cover.If you are were it freezes make sure you drain water down below skimmer and drain filter and hose`s..Buy a test kit to test water if your not sure chlorine content.Pool supply should be able to give you a closing instruction sheet on how to its just lack od oxygen. replace the water and fit a pump

How can we clear up our water? I 've boosted it 2 times. test strip says low. Still greenish.

Backwash your pool or clean your filter well. Then try putting in green algae algaecide and a clarifier. They are both fairly cheap. Then run your filter for several hours.

Pool water is green

I'm assuming that you have already shocked it with chlorine and brushed it well. If not, that is where to start.
You may want to check your filter to make sure it is functioning correctly. If it is a cartridge it should have no holes or tears in it. If it is sand it may need to be cleaned out. There are products on the market made for that purpose.
Assuming the filter is working, you should use a clarifier to turn the small particles into bigger ones that the filter can catch. If the particles are small enough they will pass right through the filter and blow back out into the pool. This is especially common on sand filters.
I've seen people spend literally hundreds of dollars on shock and algaecides trying to kill algae (that is already dead) because the pool stays green. The aggravation and expense can be huge, that is why it is important to be sure that you are treating for the right problem.

We got a above ground salt water pool an it's turning a little green what would be the best thing to put in it.

The first thing to do is to shock it with vinyl to about 10 ppm. This should start the progress to blue. Follow the Intex instructions to make sure the pool contains the correct amount of salt and stabilizer. The pump, filter and chlorinator should be run continuously until the water has clarified. The chlorine should then be kept between 2 and 4 ppm. One last suggestion, the filter gets plugged more quickly when you have shocked the pool to get rid of algae so make sure you clean the filter to keep the flow up. I hope this helps.

My pool is GREEN! What do I need to do?

You can try using shock or liquid chlorine and bring the chlorine level back to 3 ppm.. 1 small bag can treat up to 10,000 gallons.. After that, raise the cycle time on your chlorinator to maintain that level...
If you do not want to use those chemicals, raise your pump cycle time to 12 hrs and your chlorinator to 10 or 11 hrs and should see some results within a few days... The chemical method should yield faster results... Good luck...

You can cloud your water by adding chemicals that are incompatible. You will cloud the water if you simultaneously add a water clarifier and a chemical to inhibit the buildup of lime scale. You will cloud it if you simultaneously add chlorine and scale inhibitor. You will also cloud your water if you simultaneously add soda ash and a chemical to increase the hardness of the waterResources recommends sodium hypo, lithium hypo, dichlor or calcium hypo to superchlorinate water until it contains 10 parts per million (PPM) of free chlorine.

Pool filter not doing its job

try using a clarifier that you add into the skimmer such as Clearex 500.
The flocculent only makes particles drop to the pool floor, a liquid clarifier actually coates the sand and will filter smaller particles. Also, check the o-rings on the backwash valve. If the o-ring(s) are damaged it may be letting some water bypass the filter.

I think he meant not to MIX them. Don't put them in together.

If your water is still green, it definitely needs algaecide. Be sure you get the bottle that says it will KILL algae, not the preventative. (only difference is the concentration of the product.....preventative is diluted more).

After adding the algaecide you will have cloudy water looking like very very tiny white things floating in your water. Buy a bottle of clarifier to help solve this issue. It will allow the 'dead algae' white stuff to clump together and be vacuumed up. Water will be clean and clear in no time!

Hope this helps. Good luck!

My pool water is a little cloudy, the test strip says everything is ok what should I do?

you can use a clarifyer but most likely you are not filtering enough.
A pool needs turned over At Least 3 times in a filtering cycle. Figure out how many gallons an hour your pump will do and then filter accordingly.
If you have 7000gl and your pump is 2000gph then you should be running you pump 10 1/2 hours a day/night.
