You know, that's the attitude, there's nothing wrong with that overflow! It should be pretty quiet, the one on my frag tank is really quiet. It's just not as popular style, but it could be fun to have a little bit different type and you can see your mangroves growing thru the glass. Get some red dragon macro algae and put in there and it would be pretty neat with the red/green combo in there... but that's just my random thoughts. I've been wanting to get some red dragon macro algae for a while now, that stuff is pretty cool looking IMO. Good luck!
