I started to notice an algea problem about three weeks ago when I came home from Indiana. I left about July 15. Before I did the water change and everything was running fine. Two weeks later I come home to see that my tank had a bunch of green algea on the front, a lot of what looked like brown/black fuzz all over the plants and rock substrate. On my Betta log there appeared to be a bunch of white slime. I thought that a large water change and a little bit of salt could help. Well it got worse and now the front of my tanks is a nice shade of green and the plastic plants and rocks have purple algea growing on them. And the 'white slime' is purple as well. What should I do now? I would like to cycle the tank but that is pretty hard to do without a kit, so I treat my tank as uncycled, changine out about 12 cups every week.
Other info that may help:
My tank is 5gal.
Weekly water changes of approx. 12 cups
Light is on for about 13 hours; from 7A.M until about 11P.M.
All artifical decor. Plants are all plastic.
One Betta fish, only tank occupant.
Basically I would like to know what is going on and how to fix it and prevent it from happening again. Obviously I am going to have to clean the tank out, but that would mean killing what little beneficial bacteria I may have. Being a uncycled tank it probably doesn't matter much. Should I add anything? Plants, maybe a shrimp if my Betta tolerates it?
