<p>The present invention relates to an apparatus for supplying oxygen into fresh water in a fresh water tank. More specifically, the apparatus includes: a pump which sucks and discharges water with air; a first transferring pipe which transfers water and air and decomposes air finely; a main tank which stores water and fine air to swirl and discharges water and fine air to the outside; a second transferring pipe which is opened and closed while transferring water and fine air; a sub-tank which stores swirling water and swirling fine air and discharges the same to the outside; and a diffuser which discharges water and fine air. Therefore, the apparatus can maintain an environment of fresh water to while increasing the amount of dissolved oxygen by supplying air, decomposed to be fine and provided with water, into fresh water in the fresh water tank.</p> |
