with the odd clam. What would be the optimal flow for a tank like this? It's roughly 48in x 13 in x 20in
Shoot for 10x - 40x the display volume per hour for total flow through the display tank. So for a 55g tank you are gonna want 550 gph
- 2200 gph
With a sump / refugium you are gonna want to shoot for no more than 20x the tank volume per hour although 10x is the common shooting point.
So if you figure 200gph in flow from your sump you are going to want to add 350gph - 2000gph in the display with powerheads or other filters.
Danner Mag Drive pumps are pretty good, just be sure to figure in head height as it will decrease the flow rate.
