Anyone got one ? I have and its the best £400 i have ever spent ! ( Apart fae ma season ticket !) I have the water levels with the chlorine crystals and the PH thingy to a tee so the water is clear and clean, But my question to anyone that has one is even when your NOT using the tub do you still put in the dailly intake of chlorine granules ?..Every morning i throw in 2 teaspoons off chlorine granules as the manual tells me to do so so by the time i get in it later on the water is crystal clear but if i was to not use my tub for say a week i wasn't sure if i'm still to throw in the allocated amount of granules dailly ?
