Water changes - a topic discussed in great detail throughout R2R. Should we do them and why? How often? How much at one time? The questions go on and on. Well this thread/poll is meant to answer only one of those questions - How Often? I'm more curious as to the frequency of those that do utilize water changes as part of their husbandry. So cast you vote in the poll and tell how frequently you change water if in fact you do.
