Does anyone know of a product that can be put in rodent drinking water to stop it going green ? We change the water twice a week but it still goes green, obviously the stuff you put in ponds is no good it must be harmless to drink.
My wife says her Dad used something in the UK for aviaries but can't remember what it was called.
Thanks.
