I'm gearing up for the arrival of my new IM 150 EXT Lagoon next week. Right now, I’ve got a 60 gallon custom setup rocking a single MS xf330 powerhead on the back wall, which seems sufficient because my return pump is a tad overpowered and does a solid job creating good water flow on its own. But with the new tank on the horizon, I thought it’d be wise to add another XF 330. I'm planning to position it vertically at the back corners, aimed toward the front glass. I also have a spare Jabao gyre that I could set up horizontally on the back, firing forward to complement the setup. I’m thinking of running all three on a random flow setting to create a gyre flow effect. Has anyone tried using two XF 330s in a 150 or 200 gallon setup? Would love to hear about your experiences or any tips you might have.
