Do fish need some sort of dead spot so they can relax? Or constant circulation everywhere is fine?

they don't need a dead spot. you can use timers on your power heads to cut down the flow at night if you like, but it hasn't mattered to any fish i've kept.
Phranque said:Most fish live on reefs, which have tidal currents, so circulation everywhere is fine, as long as it's not overpowering...... plus you want to prevent dead spots to avoid nitrate build-ups (assuming reef since it's in the SW & reef section).
