Hello, I just set up my new sump and reefmat (RedSea 500). However, after about a week, I noticed the water movement is nonexistent (Pretty Still). I also noticed a film-like substance starting to form on the top layer. I currently have my COR 20 set to 30% (108gal) Synergy 34 Sump. Any recommendations would be greatly appreciated.
