We’ve had an email from Linda:

i want to use the water from my hot tub on the garden, it is a great waste to just put it down the drain. the water has chlorine in it.

if i drain the water into water butts, is there any way i can remove the chlorine from it to make it safe to water my garden?

This isn’t something I know a lot about – I know people use filters to remove the chlorine from tap water but that’s in a lot lower and smaller quantities than a hot tub.

So anyone with more watery experience got any ideas?
