Who Gives A Fish Forums

Setting up a new 75-gallon mixed reef and struggling with flow. Got two Nero 5s but can't figure out the best spots. Tried front corners pointing at each other, but my Acros aren't happy. Any tips?

I've had success with one on the side glass, mid-height, angled slightly upward. The other should go on the back glass, near the top, pointing diagonally across the tank. Creates a nice chaotic flow without blasting anything.

My tank's a mess. Flow's too strong, everything's dying. Don't know what to do.

Dial it way back, dude. Start at 30% power and bump it up slowly over a week. Corals need time to adjust.

I run mine in pulse mode, alternating every 10 seconds. Gives a more natural surge without hammering the corals. Also keeps detritus from settling.

Yep, pulse mode's the way to go. My LPS love it.

Had the same issue in my 60 cube. Moved one wavemaker lower, near the sandbed, and it made a huge difference. Now the flow reaches everywhere without being too intense.

Anyone tried the gyre flow pattern? Heard it's killer for SPS.

Yeah, but it's sketchy with mixed reefs. My Zoas got pissed and closed up for days. Stick to random flow unless you're SPS-only.

My clownfish keeps riding the flow like it's a rollercoaster. Not helpful, but hilarious.
