i have a frogspawn in the far right of the tank that gets tossed around big time.
i have my flow set up where about 3500gph sweeps across the tank in a big wall of flow. it goes to the right for about 15secs, then stirs for 15secs, then to the left for 15sec, and stirs again.... repeat, repeat, repeat.
long tentacle LPS can adjust to high flow over time, but they dont wanna be blasted directly.
