So my tank has some serious Brown Algae issues. It sits right next to a window, so it's to be expected. And I actually like the look of some Brown Algea... it gives my tank a more aged and natural feel. I'm not into that crystal-clear, perfectly clean tank look... I love the more natural tanks that look like they have their own ecosystem... if that makes sense. It's also nice that it helps with nitrate levels. But my Brown Algae has gotten worse than I would like. Where it used to be small patches on the back of the glass and a little on the plants and decorations, it's now EVERYWHERE. So instead of it having a roughed-up, natural feel, the tank now just has a dirty feel.
I would like to stay away from chemicals. What are some great fish/snails I could add to the tank to help with the algae? These would obviously have to be compatible with goldfish. Also, what would the QT procedure be like? How are they when it comes to salt and other additives one might put in a goldfish tank? And could these fish live completely off the Brown Algae in the tank (trust me, there's a lot), or do I still need to supplement with algae wafers and whatnot?
