I've noticed in the last month or so a brown line of what looks like algae (?) just below the top of the gravel on the glass. Is this normal? Do I need to do anything different? I rub off what I can when I do water changes every couple of weeks. It's a 46g, temp 78-80F, mostly real plants & a few silk. Weekly 50%+ water changes. I add Flourish & Excel once a week. Lights are on 8-9 hrs per day. It does get a little indirect sunlight in the morning.
It's hard to tell but here's a pic.
