Swimming Pool Professional Chlorine TCCA 90 granules (1 kg)

Works well.My pool had turned green. I opened up the pack and emptied the contents into the pool . Shocked the pool. It was back to blue overnight. Big relief . Thank you.The rate is a little too high and I have found another product online on Amazon which is a couple of hundreds cheaper. Haven't used it yet.... Let's see..

The product is damaging and is not good. I unfortunately open to use the pack only when the return window was closed 😔

OK

Working great

Good
