Thanks! I use the Red Sea Nano filter and it works well. I put nylon on the intake so not to suck up little shrimp and as long as you clean that once a week it should have no problems. No filter at this time, but the light produces lots of heat and it is in my living room, the most regulated room in the house, so far no issues with temp.thefirethief said:Rowangel. Amazing. Really looks so good. What kind of filter is that you have, and do you have a heater in there somewhere? Im looking at what options I have for a small external filter, but Im struggling to find anything.
