Is this more effective than non chlorine shock ? Thanks** A: Only a day at the max. You can shock the pool in the evening and you can swim the next afternoon. **Q: My pool is very green due to algae will get rid of the algae please** A: Yes but the amount required will depend upon the volume of water. Mix the shock dose in a bucket of warm water, start the filter pump and pour the mixture into the pool at various points. Leave the pump running for at least 6 to 8hrs initially during which time you should see the water begin to clear. If the pool is badly affected more than one treatment may become necessary. The dead algae will collect on the bottom of the pool and the should be vacuumed to waste. Hope this helps. **Q: How much will I need if a 10,000 gallon pool turns green ?** A: Approximately one kilogram if it's a swimming pool ## Customer Reviews ### ⭐⭐⭐⭐⭐ Strong and easy to use *by T***E on 30 April 2024* Follow the instructions and these are great.
