I added a really pretty kole tang. I just couldn't resist at the store. Now my black clown is doing her best to kill the poor thing. I really don't know what to do about the aggressiveness of this clown. I even had her kill a damsel once... I put a clay pot in hopes that she would just use that as her territory rather than the entire 70 gallon tank, but it seems not. This kole tang seems to be a fighter though, we'll see how it goes...
I got another fluidized sand bed filter cheap from someone breaking down their tank. I really like these things. For some reason this one has been getting clogged a lot more than any of the others I can remember, I guess I never ran them with such large grains, but that's ok. I will use it like mechanical filtration and clean it out every few weeks.
Lastly, I started an experiment with peroxide. On another forum someone suggested that it can act as a mushroom growth stimulant, so yeah. Seems to be working well already!
I think I am going to ditch the little skimmer when I move, it isn't doing anything.
