Less flow, better polyp extension

[Acrofiend]

Hi I had one of my pumps go out last night and I noticed the best polyp extension I’ve ever had. I know there’s many threads about this but would you recommend removing the pump or putting it back on? I’ve always gone by how the corals look. So I’d assume this is better for the acros.

Sounds like a good observation. I think I would replace the pump but put it on a timer to go off for awhile each day(night?) and observe how the coral responds over time.

The polyp extension is typically understood as a feeding activity. If the current is to strong then they will retract , ime. When current goes to zero I see a lot of hyperextended polyps, but I would not keep the current at zero and expect improvement over time.

Lets see what other people say- great question, and observation!

u could put it back but change the position

That’s what I was thinking. The gyre just looks better on the back wall and flow for a cube is challenging.

You know how 99% of the vendors take pictures?

They turn off the flow so polyp extension is at it's max.

Not good long term for the coral. Polyp extension means absolutely 0 as far as coral health goes.

I read a post from @jda that acros only use their polyps for gas exchange? Not sure if that’s true or not.
