How frequently do you do water changes?

  • How much water are you changing for routine changes? And how often? Some say 10% per week, some say 25% per week. Some even say every 2 weeks is good. I’ve been doing 10% weekly (or sometimes bi-weekly) but curious on what others are doing. 🐠

  • Honestly, very rarely. I maybe do a 10-20% change once a month dependent on what is going on in that tank.


    For saltwater related setups I tend to do them more often like weekly or bi-weekly dependent on the tank size and what’s in there.
