Thanks! I thought something like that could be going on. I've got a small space where to put them (Probably that's the only place unless I do something) because anywhere else they can be seen from my neighbour's second floor. Damn... I'll turn off the water heater tomorrow.

Anyway some conclusions; they've practically always faced the same way so now that I changed them they reacted. Probably they can get used to chlorine little by little or if they are exposed to it since they germinate. Anyways I won't expose my babies to chlorine unnecessarily.
