Octos and some snails will eat it. Your best to use a plastic paint scrapper just over the intake of your siphan tube when doing a water change. Don't just let scrapped off brown algea just hang in the water. This can cause an eco disaster in the tank. LED lighting may be an issue as as long as you don't have inverts, you can use mineral exhorbant materials in the filter.
I just live with the stuff until water changes.
