If the water looks good and you simply want to boost the chlorine level a bit, add 1 bag per 20,000 gallons. If the water is hazy or cloudy, use a full bag per 10,000 gallons. Or, if there is algae, use 2–6 lbs per 10,000 gallons, depending on the extent of the algae bloom.
Use a quadruple dose of shock. One pound of shock treats 10,000 gallons of water. So if you have a 20,000-gallon pool, and your water is dark green, you'll need 6 bags of shock. That's a triple dose.
Adding too much shock can result in excessively high chlorine levels in the water, which can irritate swimmers' skin, eyes, and respiratory systems. 2> Damage to Pool Equipment: Excessive chlorine levels can corrode and damage pool equipment such as pumps, filters, heaters, and pool liners over time.
Now you add chlorine shock. Use a double dose for light green water. or a triple dose for dark green water. Then you're gonna run your filter as the shock works. Overnight. the shock will kill the algae. and the filter will help pick up the remains. Finally clean your filter.
Steps for Preventing Algae
If your pool is used frequently, shock it at least once a week.
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.
If your pool is green and cloudy, it's likely an algae problem. Algae can persist in a pool even after shocking. A green pool – especially one that turned green overnight or after rain, can also be from a pool pump that isn't properly circulating water or an issue with your filtering system.
Cal-hypo shock is ideal for chlorine-based pool systems, especially when dealing with algae blooms or bacteria outbreaks. It's highly effective in clearing cloudy or murky water caused by heavy organic loads.
If the water looks good and you simply want to boost the chlorine level a bit, add 1 bag per 20,000 gallons. If the water is hazy or cloudy, use a full bag per 10,000 gallons. Or, if there is algae, use 2–6 lbs per 10,000 gallons, depending on the extent of the algae bloom.
It's all to do with your pool's pH. Pool expert Rafi Friedman told me that 'Pool shock works best with a balanced pH. If your pool's pH is too high or too low, the shock won't be effective. Ideally, your pool's pH should be close to neutral, around 7.2-7.4, before shocking.
Depending on the size of your pool, give the shock time to circulate so it can kill any bacteria and rebalance your pool. If you've got any pool toys or brushes that you want to disinfect, now's the time to drop them in the pool. Most shocks will take about 8–12 hours to work.
Make sure your pool is free of any waste that may hinder the pool chemicals working as they should. Remove any leaves and other loose debris with a pool skimmer.
Run your filter 24 hours a day and backwash 2 times a day for the quickest results. Run the backwash cycle for 60 - 90 seconds. The more you run your pool, and the more you backwash the filter, the faster the pool will clear up.
Shock the pool with chlorine every day until all the green is gone (possibly 3 to 4 days). 2. Run the filter 24 hours a day and backwash every day until the green and then cloudiness is gone (usually up to 7 days, sometimes as long as 2 weeks depending on the filter).
As pool experts, we hear this question a lot. The short answer is no; baking soda will not clear a green pool, as it cannot kill algae. Adding baking soda to your pool will, however, raise your alkalinity and pH levels and can be helpful when dealing with small growths of black algae.
Brush the pool after adding shock to help eliminate the risk of bleaching your pool while simultaneously loosening up whatever algae is on your pool's finish (if your pool walls or floor are slippery, that is algae).
Is it possible to shock your pool too much? Yes—excessive shocking of your pool will keep it at an elevated chlorine level. This will cause irritation of the skin and eyes as well as excessive wear and tear on your pool filter system, including excessive corrosion of all metal parts.
So How Much Shock Treatment for Yellow Algae? Recommended Treatment: 3LB of Calcium Hypochlorite for every 10,000 gallons of pool water.
Pools can immediately turn green after being shocked when they have metals like copper in the water. These metals oxidise when exposed to high levels of chlorine, which makes the pool water turn green. Adding a metal control product such as Zodiac Metal Remover will help to restore the pool water.
Shocking your pool regularly will help to keep the water clean and free of contaminants. You should aim to shock your pool about once a week, with the additional shock after heavy use. Some tell-tale signs that your pool needs to be shocked are cloudy, foamy, green, or odourous water.
