Quick Answer: Can I Use PH Up And Shock At The Same Time?

Should I raise pH before shocking pool?

Lower the pH before shocking, 7.2 – 7.4 is best for shock efficacy.

Dilute pool shock in a bucket of water for vinyl liner pools.

Do not use a solar blanket until chlorine and pH level are normal.

If chlorine level drops to zero within 24 hours, Repeat the shock treatment..

What pool chemicals should not be mixed?

Most common swimming pool chemicals are incompatible with each other and should never be mixed. Mixing of organic chlorinating agents (such as trichloroisocyanuric acid) and inorganic chlorinating agents (such as sodium hypochlorite) can lead to fires, explosions and chlorine gas release.

Can I add pH up and alkalinity at the same time?

If you find your pH and total alkalinity levels are too low, you’ll need to add pH increaser to bump up the pH. If both the pH and total alkalinity levels are too high, you’ll need to add pH reducer.

Should I add acid or chlorine first?

The addition of the chlorine or salt will give you the pH increase. It’s not worth it to add an alkali one day, to raise the alkalinity or the pH, then an acid the next when neither was necessary!

What happens if you swim in a shocked pool?

Chlorine- based shock contains high levels of pH and will alter both your pH and chlorine levels in the pool. Chlorine- free shock has a neutral pH and will not affect any of your other chemical levels. … And in turn, it will delay your swimmers from returning to the pool.

Does shock lower pH in pool?

Pool shock. Shocking your pool is important, but if you’re using cal-hypo (calcium hypochlorite), it can raise your pool’s pH levels. Don’t stop shocking your pool, but do test all your chemistry levels consistently, especially after shocking.

Do chlorine tablets raise pH?

So, chlorine tabs lower pH and Total Alkalinity and increase cyanuric acid levels. … While pH naturally rises in gunite pools, using tablets lowers the pH. This is an added benefit of Trichlor tabs IF used in moderation.

Will baking soda clear up a cloudy pool?

Can You Use Baking Soda to Clear Up a Cloudy Pool? NO! Baking soda is a base and will hugely increase the level of pH, which actually causes the water to turn cloudy. Some people may suggest using baking soda as a quick fix if alkalinity is high, but it is not a reliable pool chemical.

Why is my pool still green after shocking it?

When pool chemicals are not properly maintained it is easy for pH levels to get out of whack quickly leading to a green pool. If you have already shocked your pool and taken pH level samples you may still need to add stabilizers or phosphate removers.

How long after adding pH up can you add shock?

8) How long after adding chemicals can I swim? Alkalinity Balance, pH up, pH down, Calcium Balance, Water Stabilizer, and clarifier are all swim-safe chemicals. Wait about 20 minutes, and you are free to swim. We suggest adding algaecide, Super Erace, and shock at night, after everyone is out of the pool.

Can I add shock and chlorine at the same time?

All of these dissolved minerals will hold in the solution of your pool water; which can result in staining and cloudy pool water.

Why is pool pH always low?

The most common cause of consistently low pH level in pools is using chlorine tablets, or stabilized forms of chlorine, which have a pH level of around 3. Acidic rainfall and heavy leaf debris, and dirt/mulch can also lower pool pH level.

Does shock affect pH?

Chlorine based pool shock (Calcium Hypochlorite) has a high pH, and will naturally raise the pH level of your swimming pool water, in addition to changing your chlorine level. … Each time chlorine based (Calcium-Hypochlorite) swimming pool Shock is added to your water, you are adding calcium to the pool.
