I am a college student who wound up getting a Betta fish two weeks ago in a white elephant party at work. I had an empty tank, and all the stuff from my previous planted tank so I said why not and set up a quick tank for the fish. The tank is still cycling, and it started into an algae bloom. Here's the issue I am leaving for two weeks to go home and spend Christmas with my family, and I leave tomorrow. I planned to do a 50% water change tomorrow before I leave for the airport, leave the light off but the window open (the tank is in the window) and hope for the best. Now I am worried the algae bloom will get excessive while I am gone. Any tips to help mitigate it as much as possible while I am gone?
