I have a large piece of decor in my tank that has algae on it, and I can't get rid of it. It doesn't seem to matter how many times I take that piece out and scrub it down, it still comes back. It's not affecting the plants or anything else in the tank in any way, but it's gotten really annoying to look at. Do you have any suggestions on how to get rid of it?
The tank gets 7 hours of fluorescent light from an Aqueon Full Spectrum 15W T8 18" bulb a day and I dose it with Seachem Flourish weekly.
Temperature: 76 F
Thank you for your input.
