In my 20L, I have 2 Koralia #1's and a Tunze Reef Pack (Nano Skimmer and Filter). The problem is, I'm not sure if I have enough flow. Right now, I have 1 Koralia in the back right corner about 1/4 was down pointing slightly up and at the center front glass. My other Koralia is on the back glass 1/2 way down, off center also pointing at the front center of the glass. And finally my Tunze Reef Pack is in the back left corner up as hight as it can get, leaving a few inches below the unit.
One problem I'm having is that I have very little if any flow at all going under the Tunze. I was wondering how can I, or should I even have flow going under the unit. If I have to reposition the unit, I will, I just can't figure out at way to get good flow everywhere. I'll try to take a picture tonight for a better description.
