The best time of day to shock pool is when the sun is down. So, experts recommend shocking your pool in the evening or at night, to make sure it does its job. Shocking during the day can be ineffective as UV rays from direct sunlight significantly reduce free chlorine levels.
When diluting, always add the chemical to the dilution water to prevent splash out of the chemical. Liquid chlorine is not stabilized and will burn off quickly in sunlight. Therefore, it should be administered in the evening, after the sun has set.
As long as you test and actually KNOW what you have and what you need in the pool, you can manage it any which way that works to keep the levels up. Around here we usually suggest that you keep your chemicals "separate", that is, add exactly as much CYA as you need, then add exactly as much chlorine as you need.
You can either feed the liquid chlorine through your pool's mechanical chlorinator, or pour the solution directly into the pool. This is preferably done when the sun isn't out so that you achieve the best results. For additional help or pro-tips, contact the pool professional at Iron Man Pool Care.
Liquid chlorine — In general, it's a good idea to wait at least four hours after putting liquid chlorine in the pool. The size of your pool and the amount of chlorine added does play a factor in this, too. Once your levels reach 5 ppm or lower, you're ready to swim.
Liquid chlorine and granular shock have the same active chemical that sanitizes your pool, what changes is the strength and the way you use it. Liquid chlorine is less costly, unstabilized and comes in liquid form. Granular shock is stabilized and comes in a solid form that dissolves in your pool.
Welcome to TFP. Proper testing is the only way to know for sure how much to add each day. We usually figure about 2 to 3 ppm FC loss per day. You can use the pool calc to get a ballpark of how much bleach that it's going to take each day.
All pool chemicals, aside from unstabilised liquid chlorine, are good for up to three to five years as long as they're stored in a cool and dark place away from sunlight and they're packed in air-tight containers.
Sodium hypochlorite (also known as liquid chlorine) is another frequently used option for shocking pool water. This is a common choice in pool shock because you can pour the solution directly into the pool without having to dissolve the chlorine in water beforehand.
Liquid chlorine is preferred over chlorine tablets by pool professionals however home swimming pools will benefit too. Liquid chlorine quickly raises or maintains chlorine levels without raising stabilizer. Chlorine tablets maintain chlorine levels and add stabilizer to the pool water.
75 ounces per 3,000 gallons every week. Initially you will need stabilizer to protect the chlorine from the sun. This is added at a rate of one pound per 3,000 gallons of water.
So, how much liquid chlorine to shock a pool with algae? A minimum amount of 30 ppm is what needs to be considered to resolve the problem.
The best time of day to shock your pool is in the evening. This is because the sun's rays can affect the effectiveness of the chlorine by dissolving it too quickly, before it has a chance to rid the pool of contaminants and clean the water.
Sun Down – You'll want to shock your pool in the evening when the sun has gone down. This gives your pool plenty of time during the night to free the chlorine and clean the water. In the morning, you should be able to enjoy your pool. If you shock your pool during the day, the sun's UV rays will dissolve the chlorine.
It's often recommended to shock your pool once a week. If you don't do it every week, you should at least do it every other week. This is necessary to maintain your pool's water chemistry. If you have a lot of people over in your pool or have a party, you may want to shock your pool more frequently.
Liquid pool chemicals, on the other hand, tend to have a shorter shelf life. For example, dry pool chlorine will not expire for a long time, while liquid pool chlorine will expire quickly. If you have any pool chemicals in liquid form, they will only last up to two months before they begin to become ineffective.
Generally, you should maintain the pool's chlorine level between 1 and 3 ppm. Thus, if the chlorine level is already 1 ppm and you want it higher, add 0.00013 ounces per gallon to raise the chlorine by 1 ppm.
Dichlor is perhaps the most “best of all worlds” chlorine sanitizer. It is typically found in concentrations of 60-65%, which is comparable to cal-hypo. It is a powder sanitizer, which makes it easier to spread or broadcast around the pool than chlorine tablets.
For the greatest protection against algae, bacteria, and cloudy water, Intex pools should maintain a chlorine level of 2.0-4.0 ppm at all times. If you opted for the Intex Salt Chlorinator, you can make your own chlorine by adding the correct amount of Pool Salt to the water.
Using liquid chlorine raises the pH of the water.
When added to water, liquid chlorine (which has a pH of 13) makes HOCl (hypochlorous acid – the killing form of chlorine) and NaOH (sodium hydroxide), which raises pH.
You should wait one hour per pound of shock product added, and then test the water to confirm the pH and chlorine are in the proper range before letting anyone enter the pool. As a reminder, you want your pH to be between 7.2 and 7.8ppm and your free available chlorine to be 1-4ppm for safe swimming.
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.
In the industry it is recognized to have the pool run for 3 hours at a bare minimum up to 24 hours. 24 hours really is overkill but it'll ensure the water is completely mixed with the chemicals.
Wait times for adding pool chemicals
The wait times between adding pool chemicals is usually around 10 minutes each, as that is also sufficient time for the chemicals to mix in the water. Users also under normal conditions can swim roughly 10 minutes after adding chemicals.
