How often to chanmge aero cloner water?

[Linkedlight]

Did a search, but my google-fu is poor and found nothing useful.

I tossed them in yesterday and they look lovely and happy. I just need to know how often I change the water int he 2 weeks that they are in there.

Cheers

I change mine once per week. I also bleach it out once a month. Changing out the water once a day is most likely the best for longevity of the equipment.
