Does it matter what kind of pool shock you use?

The type of shock you should use will depend on your water chemistry and the reason you're shocking. If the water is green, you should use a cal-hypo shock. However, if you're shocking as part of weekly maintenance and your pool looks clean, you can use sodium dichlor, potassium monopersulfate or sodium hypochlorite.

What is the difference between pool shock?

How do I choose shock for my pool?

What Type of Shock Is Best?
  1. If your calcium hardness level is high, avoid calcium hypochlorite shock, which will contribute to even higher levels. Choose Di-Chlor or Non-Chlor shock instead.
  2. If your cyanuric acid level is hHigh, avoid Di-Chlor shock, which is stabilized and will contribute to even higher levels of CYA.

Should I shock my pool once a week?

What happens when you mix Coke and pool chlorine?

In the coke there is a small amount of phosphoric acid, which acts as the reactant. When the phosphoric acid reacts with the pool chlorine, calcium hypochlorite, it releases a gas. The coke and the pool chlorine also create an exothermic reaction, which means that heat is released. That is where the steam comes from.

How many pounds of shock do I need for a 30000 gallon pool?

How much shock do I need to shock my pool? A simple ratio and a standard rule of thumb to follow when you shock your pool is to dissolve one pound of either calcium hypochlorite or sodium dichlor for every 10,000 gallons of pool water.

Can I add shock and chlorine at the same time?

It Should Not Be Done Together

This is because when you mix chlorine and algaecide together, it renders both of them useless. Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM. Only then should you introduce algaecide to get the best results.

Can you over shock a pool?

Can you put too much shock in a pool? SKIMMER NOTES: It's unlikely but it could happen. It would take a lot of shock to really make the water unsafe for swimming. The best way to make sure you're safe to swim is to test your pool water and make sure free chlorine levels are between 1-4ppm for healthy swimming.

Is Pool Shock same as chlorine?

Shock is chlorine, in a high dose, meant to shock your pool and raise the chlorine level quickly. Chlorine tabs (placed in a chlorinator, floater, or skimmer basket) maintain a chlorine residual in the water. You do need to use both tabs and shock.

Can I use pool shock instead of chlorine?

SKIMMER NOTES: No. Chlorine and shock are not the same thing.
