What do you do if the total alkalinity is high or low in above ground pool?

Answer 1

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.

Answer 2

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, it 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.

Answer 3

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.
