HCA: Hermit Crab Association

Hi. New member here. I've been reading over posts and can't seem to find an answer on how often to change out water in pools. I've been changing every 2 or 3 days when I see substrate or other stuff floating around. Is there a hard fast rule on water changes?

In the water guide thread it's recommended to do it everyday. But it can be stretched to 2-3 days before changes. You can read all about it at the bottom of this thread http://hermitcrabassociation.com/phpBB/ ... 25&t=92553

Thank you. I missed that part.

Personally I change my water every other day (although I've gone 2-3 if sick or something), but if the crabs drag in moss or food or whatever I change it ASAP since decaying organic matter isn't a good thing to leave in there
