What would you like to do?
Add muriatic acid to lower your TA to a more acceptable level...around 100, but no higher than 140. Then balance with bicarbonate of soda if necessary to increase ph. Once you get to an acceptable TA add an algaecide or shock the pool to get rid of the algae on the bottom.
Just triple shock with liquid chlorine; for your pool 2.25L. You probably need to add water (because of splashing) quite regularily so I wouldn't bother lowering the alkalinity.

Thanks for the feedback!
First you should find where your pool water Total Alkalinity SHOULD be (depends on total hardness of the water) and then adjust the TA. Then adjust pH. E-mail me for full ins…tructions.
Why would a 12 foot by 3 foot vinyl pool you shocked three times and got the free chlorine level to 5 and the pH to 75 now have green cloudy water if there was 0 alkaline in the water used to fill it?
Try adding some algaecide. It sounds like you have an algae problem. How often are you shocking your pool. If it's extremely sunny, then your free chlorine will be reduc…ed quickly. I have had good luck with adding 5 gals of liquid chlorine to clear up algae and then follow up with algaecide. ou could use less, as my pool is 4x28. Don't forget to run your filter a couple of hours a day to turn over the water. Good Luck. New answer: Disregard the above answer for the following reasons. Your fill water may be from a well or other source even though it is "city" water. Cities mix their water sources. This sometimes results in either somewhat milky cloudy ( which is sometimes called "air entrained" ) or it comes in a cloudy green. Further, 2 hrs. per day is not sufficient to maintain water clarity. In most pools in the example above and larger require from 6 to 12 hrs daily and more with the combined efforts of adding the correct amounts of chemicals and sanitizer. By now your pool has most certainly cleared. Filter that green water non stop until the water becomes fairly clear then you can cut back the filter time to whatever time is required to maintain "your" own pool. Different pools with different equipment configurations require different run times. Even the pool next door will sometimes require a different regimen of maintenance. After filtration of at least 6 hrs. you can then start adding chlorine and adjusting pH. Ken
Alkalinity and pH In a pool with an alkaline pH level (7.0 to 14) you would use soda ash. If your pH level is acidic (6.0 to 6.9) when you add soda ash (sodium carbonat…e) to the pool the acidity of the water will convert the sodium carbonate to bicarbonate, which will have the effect of increasing the total alkalinity. There is no way around this reaction when your pH is below 7.0. Just make sure you maintain a pH level above 7.0. For swimmer comfort you should not have your pH below 7.4. Increasing the pH of the water without affecting the alkalinity is very easy, but there is a trick. With the pump motor on and water circulating, add the sodium bicarb. in the deep end of the pool and work your way around the perimeter. This will raise the pH with minimal effect on the alkalinity. Keep your pH around 7.6-7.8, not 7.2-7.4. Most "pool experts" tell you 7.2-7.4 but they are using an index that your local water company uses which obviously is not and should not be used for pool. There's a big difference between a water treatment system and your pool. You can't treat them the same.
Answer Add a mild acid and/or water, depending on what's being neutralized.
Answer Alage, Alage, Alage, you need to control it, and once you do your pool will be sparkling clean Response to this ridiculously useless answer: First of all, i…t is "Algae", not "Alage". And last I checked it wasn't a proper noun, so capitalizing each time is not necessary. This answer is horrible. Could you be any LESS specific? How about some tips on HOW to control algae? Second, we figured out our problem on our own, for anyone who is interested, and it is NOT an algae problem. Our pool is surrounded by trees, and the greenness of the pool was caused by tree debris that was so small (probably from all the freaking shock everyone kept telling us to put in) it went right through the filter (even after replacing the sand). We finally got a useful tip to try pool floc. You put it in the water, and within 24 hours it causes debris to clump up and sink to the bottom of the pool. We vacuumed to waste, and voila, clean sparkling pool. Let this be a lesson to all... sometimes it is NOT a chemical problem. Everyone and every site kept saying "you need to shock it," or some other worthless tip about raising or lowering the pH/alkalinity. We had a filter problem, so if your pool is green, and you've spent a small fortune shocking your pool, try thinking outside the "it's the chemicals" solution that is always given.
Why would clear pool water turn green after adjusting the pH and alkaline and shocking it according to the pool store's directions?
You need to put an algicide in your water. If there is metal in thewater, the metal will react with the chlorine shock and turn greenor brown. Certain areas of the country hav…e naturally high levelsof metal in the groundwater, so that you will have to use achelating agent every time top off your pool.
How do you balance the water in an above ground vinyl-lined pool if the total alkalinity is at 240 and your pH is 6.8?
Drain the pool Start by draining the pool half way and refilling it. That should cut the alkalinity in about half, which is about where you want to be. When it's… in the 100 to 120 ppm range, you should be able to adjust your pH properly without having to chase wild and frequent fluctuations. Chances are good that if you adjust the alkalinity to where it needs to be, the pH will be about right. You may not need to add any pH plus or minus at all. Don't waste all that water, though. Use as much as you can to backwash and rinse the filter!
For most residential pools, this is a trick question. One adds acid to reduce pH and Total Alkalinity. However, as total dissolved solids(TDS) build, say past 2,000ppm, pH of …saturation will go towards 6.0. One can measure TDS, or use an estimating rule on when to change water to reduce TDS. To calculate days between complete water change, calculate ( Pool volume in gallons/3)/(bathers per day). For example, you have fifteen swimmers per day. Your pool is about 10,000 gallons. Then (10000/3)/15 yields: 222 days between changes. In a commercial pool, say you may have 100 swimmers per day in 100,000 gallons. Then (100000/3)/1000 yields: 33 days between changes.
With the addition of muriatic acid.
pH 12 is very Alkaline. So the answer is no.
The accepted range in the pool industry is 80-120 ppm. If using isocyanurate chlorines, 100-140 is more acceptable. The reason is that as cyanuric acid levels increase, the mo…re it gives a false reading on most test kits for Total Alkalinity. Use a Taylor Test Kit and read the instructions, especially the last page where it explains the formula for getting a true TA reading.
Use Muriatic acid or Alkalinity minus to get your akalinity in line. It should be around 100 ppm. Caution this will also bring your pH down to. Then use 20 mule team borax tha…t you can buy at any grocery store in the soap asle to raise the pH. This wont afect your alkalinity. Good Luck TS
The chemical to use to lower your PH and Alkaline Levels would be Sodium Bisulfate or PH Down. While the pool is running broadcast 1lb per 10,000 gals of water and apply this …daily as needed till in proper ranges i.e. PH should be min 7.2 Ideally 7.4-7.6 maximum 7.8 and your Alkaline ranges min 60 Ideal 80-120 and maximum 180. I am not sure how you ended up on the high end but something to consider in the future is to to add chemicals as labeled, one to two pounds at a time only you can always add more if necessary to bring your pool to correct levels. Also, certain factors can cause your PH levels to change including the following: TriChloro sticks or tabs -lowers PH Bromine Tablets -lowers PH Liquid Shock, Super Shock and Lithium -raises PH Fresh plaster can raise PH Adding Water or Rain can raise or lower levels Swimmers and swimmers waste lowers PH ***Please note Muriatic Acid can be used to lower PH levels as well, however I would stress that this is a very potent chemical and I would not suggest a homeowner use this as a solution or store this on premises and is usually used in commercial pool situations under controlled circumstances.

Adjust alkalinity first
Call in the pros. Take a sample of your water in a new, quart-sized Zip-loc bag to your local pool supply store. They can test for many more variables than are available in a …home test kit, and will recommend exactly which chemicals you need, and how to use them.
No. Alkalinity neutralize the acids. Based on how much you put in, will cause a reduction in your pH levels.
Alkalinity readings for your pool is quite essential. When you increase your alkalinity, that makes it so your pH is more resistant to change due to weather, leaves etc
