Trim down a magic eraser for the algae and scrub it. I use it on my acrylic tank with no issues.Updated top down on this guy.
Keep getting top downs because the front has a nasty really rough spotting algae on it and the only way I think I'm gonna be able to get it off is a razor, which I'm sure will scratch it up since it's acrylic.
The "competition" is officially over, only @Mhamilton0911 and I seem to have made it to the end.
Not sure if I'm going to keep it running as my "I didn't order this freebie coral and have no where else to put it" tank like I have been, or what. A small part of me was thinking about moving it up to a slightly bigger tank (like, a full gallon). We'll see.
