Fish Tank Maintenance Tips: Try to change some of the water in the tank on a regular basis. Small frequent (weekly or every two weeks) water changes are better than infrequent large water changes. Small water changes will cause less stress and shouldn’t interfere with the biological cycle in the tank. If you have a larger tank, get a Python Vacuum or a Lee’s Premier Ultimate Gravel Vac. These vacuums make doing water changes a breeze. Gravel vac only half of the tank with each water change. Switch sides on the next water change.
