Why so many people find it so hard to calculate basic additives that they they all ask the same question, sometimes without key details so potential respondents can't help them anyway?

First - what's "Shock & Swim"? It's no good quoting trade-names because anyone unfamiliar with it won't know its specific dose rate.

Second - what do you mean, 15x42 "Easy Set" pool" Again, that's only any help to a fellow owner of the same pool. You should quote the water depth, or depths if it has deep & shallow ends, width & length, AND whether that's feet or metres. (I suspect feet here as 42m makes a very long pool for a private garden!

1) If you don't already know it, calculate the water volume in EITHER cubic feet OR cubic metres. That is basic school text-book or engineers'-handbook geometry.

If using cu ft then multiply by the appropriate factor for US or UK Gallons.

If using cu m then x by 1000 to obtain the litres. (1 cubic metre of water = 1000 litres)

DO NOT MIX ft & galls with m & l.

2 ) Establish the existing concentration hence additive qty needed, by dip-strip or meter.

3) Now read the label on the disinfectant container or leaflet to establish the dose per so-many galls or litres.

4) Divide your pool's volume to find that "so-many" factor then multiply the dose rate by that, & adjust the answer to suit the existing concentration. .

E.g. if your pool holds 50 000 litres & the instruction say "1kg of granules per 10 000 litres for 2ppm" then it's (50000 / 10000) x 1kg = 5kg for 2ppm rise.

So if there are already 1ppm of bleach in the water, you need add only half that, i.e. 2.5kg, to give a new concentration of 2ppm.

5) last but not least... Now write down the water volume and the amounts of each additive & keep the notes in a safe place!

Is pool shock the same as chlorine?

Pool shock typically contains a higher concentration of chlorine compared to regular pool chlorine products. Pool shock is used to quickly raise the chlorine levels in the water to kill bacteria and algae, while regular pool chlorine is used for maintenance and to keep the chlorine levels stable over time.


How to use pool shock effectively for maintaining clean and clear water in your pool?

To use pool shock effectively for maintaining clean and clear water in your pool, follow these steps: Test the water: Use a pool water testing kit to check the chlorine and pH levels in your pool. Calculate the amount of shock needed: Refer to the instructions on the pool shock product for the correct dosage based on your pool size and current water conditions. Dilute the shock: Dissolve the pool shock granules in a bucket of water before adding it to the pool. This helps prevent staining or damage to the pool surface. Apply the shock: Pour the diluted shock solution around the perimeter of the pool while the filtration system is running. This ensures even distribution of the shock throughout the water. Wait and test: Allow the shock to circulate in the pool for several hours or as recommended on the product instructions. Test the water again to ensure the chlorine and pH levels are within the desired range. Repeat if necessary: If the water is still cloudy or algae persists, you may need to shock the pool again or consult a professional for further advice. By following these steps, you can effectively use pool shock to maintain clean and clear water in your pool.
