It could be, but sounds more like hi alkalinity. Check your TA ( total alkalinity ) It should be between 80-120 ppm. You can bring it down using muriatic acid if you need to.

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 that you can buy at any grocery store in the soap asle to raise the pH. This wont afect your alkalinity. Good Luck TS

Muriatic acid is most commonly used in swimming pools to lower the swimming pools PH and to lower the pools alkalinity. You should use caution when working with muriatic acid. Not only can it stain your clothes, pool deck, etc, but if you inhale too much it can cause tissue damage. Always consult a professional when working with chemicals that you are not completely knowledgeable about, some swimming pool chemicals when mixed wrong can have a chemical reaction and catch on fire.

Novices should not use muriatic acid for gardening. It is harmful to persons and harmful to the environment, and is recommended only for professional use.

Yes there should be no problem with that.

Extremely carefully. Muriatic (hydrochloric) acid is not something you should be messing around with if you don't know how to handle it safely.

Muriatic acid can be used to clean dishwashers. Muriatic acid is very strong and should only be used occasionally for cleaning the dishwasher.

Muriatic acid will lower the Total Alkalinity. Dosage is 21 oz. per 10,000 gallons will lower TA 10 ppm. Add in the deep end of the pool, away from skimmers and lights. If using in a vinyl or fiberglass pool per dilute before adding to the pool. Note that muriatic acid will also lower th pH. You will need to adjust the pH using Soda Ash (sodium carbonate)Dosage is 6 oz. per 10,000 gallons will raise pH .2 ppm. Your pH is the opposite side of the same coin with alkalinity. To raise it use Sodium Bicarb. With the pump motor off and water motionless, add the bicarb in the deep-end of the pool, in one spot. Let it sit for 4 hours or more. Turn the pump on and allow to circulate for 2-3 hours, then re-test. Alkalinity should be 80-100, not 150 or higher. To lower alkalinity, do the same, just use acid. The chart your need in provided in the link below.

Muriatic acid added to the pool water will not remove stains from swimming pools. Unless you do an acid wash. Something that should be left to an experienced pool tech. Purchase a good test kit that will measure chlorine, pH, alkalinity and conditioner. This test kit will, after the initial test for pH and with a further test, give you amounts of muriatic acid to add to your particular size, in gallons, pool. K

You should wait at least 15 minutes before swimming after you add muriatic acid. If you can wait 30 minutes to an hour, it is even better.

It is possible that muriatic acid will damage the soil on a permanent basis. If your soil needs additional acid, vinegar works better than anything.

1000000000-20000000000 isn't that just great?

muriatic acid should work fairly well

A dilute solution of muriatic acid is used by the pros.

The Ph should never be out of its permitted range. the alkaline tunity wastewater is tested on three stages. There should never be less than 50 mg/L of alkalinity.

In some cases, soda ash can be used to raise total alkalinity. Pound for pound, soda ash raises alkalinity 60 percent more than sodium bicarbonate and is cheaper than sodium bicarbonate. The problem with using soda ash to increase alkalinity is it drastically increases pH. This can cause cloudy water and scale formation. Soda ash should only be used to increase total alkalinity if you also need to increase the pH or if only small increases in alkalinity are needed.

Muriatic acid is considered concentrated Hydrochloric acid. At STP the maximum soluble concenration is about 37.5% HCl. You will usually titrate it to 36% HCl and as low as 34% HCl. Concentrated muriatic acid is always evaporating HCl gas and the concentration is always dropping. For most purposes like "pool cleaning" they cut it to 17% HCl and still call it muriatic acid. Muriatic should have 65% water by weight on average for the concentrated stuff and 83% water by weight for the weaker stuff.

Use Soda Ash to increase the PH level. Baking soda can be used to maintain the alkalinity of the pool water. Just the opposite!!!! Baking Soda will increase or raise the alk. Soda Ash raises the pH. Muriatic Acid lowers pH. k

You may want to add muriatic acid in small amounts more frequently - say every 20 minutes. The alkalinity will take care of itself. Be sure of your test results. You may have old test solutions or an old test kit. If you have access to digital testing equipment that may be more accurate. The addition of baking soda in small amounts will raise the alkalinity. Monitor it about 20 min. after application with a good test kit. To keep your pH from rising too much add the acid as above. Keep this up until the alkalinity is close to the minimum rating for alk. Test again the next day to see of it has stabilized. If not continue the application of baking soda. This may take from hours to days to correct. If you have a small body of water, like a spa, it is easier, quicker to change the water.

It should probably leave it to a professional. They use muriatic acid.

Alkalinity should be maintained between 80-120 ppm to act as a buffer for pH. Without the buffer effect your pH would have more frequent and wider changes.

In order to not cause irritation of the eyes and skin, the pH of the pool water should be between 7.2 - 7.6. Muriatic acid is added to the pool to lower the pH if it is too high.
