What would you like to do?
If pH is 7.8 and total alkalinity is 240 and the 12'x3' pool is starting to get green stuff in the bottom what should you 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!
Why would clear pool water turn green after adjusting the pH and alkaline and shocking it according to the pool store's directions?
Answer You need to put an alagecide in your water. If there is metal in the water, the metal will react with the chlorine shock and turn green or brown. Certain ar…eas of the country have naturally high levels of metal in the groundwater, so that you will have to use a chellating agent every time top off your pool.
Alkalinity first! First check to see where the total alkalinity is in PPM, then determine how many PPM change is needed to reach your target reading. Caution, I alway aim… for 10 to 20 PPM below my ideal reading, because when you begin to adjust the pH, the TA will rise.
pH 12 is very Alkaline. So the answer is no.
If TA is low you first add sodium bicarbonate (baking soda), circulate,test again. Once desired TA level is attained adjust pH.
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.

Initially, you can't. What you do to lower alkalinity is first lower the pH to under 7.2, but not lower than 6.9. Then you aerate the pool, by creating bubbles with your brush…, or by running a water feature, if you have one. This will lower your alkalinity. Maintain this lower pH and aerating until you get your alkalinity where you want it. Then retest your pH. If it is now too low, you add Mule Team Borax, say a 1/4 a cup, and then retest. The borax will raise your pH without raising your alkalinity. See the poolforum.com for more help if needed.
No. Alkalinity neutralize the acids. Based on how much you put in, will cause a reduction in your pH levels.
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.
Green Stuff in the Pool The green stuff is one of two things: 1) algae which needs to be oxidized (shocked) or 2) copper which can be removed with a sequestering agent. He…re are more answers from other FAQ Farmers: . Like the posters above you could have Algae, generally indicated by a green growth on walls and cracks and crannys of the pool along with the water being green. Copper from perhaps a heater's heat exchanger or perhaps you used a copper based algae remover. So then what can happen is the Copper can come out of solution and show up as green water. Next do you have well water or water with a high content of iron? That will show up very green, especially when you have just put in a large amount of water to bring the pool up to the correct level. And again you will need a product to tie it up and remove and put it back into solution. Best solution to get all this back into solution or get rid of it, Please go to a swimming pool professional licensed and insured with a sample of water, they will be able to give you the professional product for your swimming pool. . 99% of the time a green pool will be from an infestation of algae. The first thing you should do is shock the pool with a strong chlorine, that will kill the algae. You then need to run the pool constantly until it has cleared it up. Chlorine will kill the algae, and the filter will remove the cloudiness that is sometimes left behind.
Adjust alkalinity first
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
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.
With the addition of muriatic acid.
Answer Add a mild acid and/or water, depending on what's being neutralized.
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.
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.
