Who Gives A Fish Forums

I've got a mixed LPS tank with Hammers, Torches, and a Duncan. The flow seems off, either too strong or too weak. What's the sweet spot for wavemaker settings to keep them happy without blasting them?

LPS generally prefer low to moderate flow. I run my Nero 5 at 30% pulse mode, alternating every 6 seconds. Keeps detritus moving but doesn't stress the polyps. What pump are you using?

Yep, pulse mode is key. I've got a Gyre 1K on random at 40%, and my Euphyllia are thriving. Just avoid direct flow, or they'll stay closed.

My Torches hated high flow. Moved the wavemaker higher in the tank and dialed it back to 20% constant. Now they're fully extended. Tank's a 40-gallon breeder, sand substrate.

Anyone tried the night mode trick? I run my pump at 15% after lights out. Seems to mimic natural currents better. Daytime stays at 25%.

My Duncan's in a 20-gallon with a cheap pump. It's set to the lowest setting, and the polyps are huge. Maybe LPS just wanna chill?

What's the ideal placement for the wavemaker? Mine's on the side, but the flow feels uneven.

Thanks for the tips, everyone. Gonna tweak my settings tonight and see how they react.

Aim it at the glass or rockwork to diffuse the flow. Side placement can work if you bounce it off a surface first.

Also, check for dead spots. I added a second small pump opposite the main one. Now the whole tank gets gentle movement.
