    Does doing a water change add Oxygen to the fish tank?

    Hello Mr Clown Loach!

    Yes, usually a water change does introduce some new oxygen to the tank and the temporary increase in the water movement will improve the oxygen exchange.

    Anything that creates bubbles in the water introduces oxygen, and also helps the oxygen exchange at the surface of the water by keeping the bioFilm away

    Yes it does, but if oxygen is a concern just run an air stone or sponge filter. If you have a HOB, the agitation to the water surface will also aid in tank oxygenation.
