If it is terribly gross, I would recommend doing a complete water change. Even though it will probably stress him out, if the tank is that covered in algae, it will help the appearance of your tank and your fish's health. Make sure to rince the plants and gravel thoroughly with hot water. Changing the filter media will definetely help!

Won't that kill my cycle? It's a cycled 10-gallon.

And won't hot water be bad for the plants? They are live plants.

I'll definitely change the filter media, then.

I just did a 3-gal water change (tank is 10) and brushed and rubbed off as much algae as I could. I'll be gone for the weekend, so the lights will be off from tonight until Sunday night. I'll start leaving the lights on for only four hours when I get back.

Are you sure I shouldn't change the media? It's pretty gross looking, it's covered in furry algae. I guess that's where the BB are, though, right?

How do I increase CO2 and nutrients?

I have root tabs in the tank for my amazon swords, aren't those nutrients? If so, I guess it's not enough.
