No big deal. How long did it take to show up? What's your lighting and schedule?

Id say for starters add a few more snails, clean the glass regularily and do a couple water changes to get those nitrates down a bit.

2 days from changing the water and cleaning the glass this brown color shows up in glass! I have a 24" t5 Ho 4 bulbs (2 blue plus and 2 coral plus)
