Got up this morning....

and a decent size acro frag is bleaching. It’s turning white from the bottom up. The only thing that’s changed is the water flow. I got a new MP40 last week and stuck it in the tank. Saturday I decided to move the MP40 back a few inches. The power head is closer to that particular frag than any other. Has anyone ever experienced flow-related SPS death?

Yes that can happen if the flow is directed towards it. I once had an acro which was approx 8 inches away from my MP40 and it lost a lot of skin overnight after i first placed the MP40 in the tank.

When i got a gyre i had some very direct flow on a tort that blew its skin off. It was only a few inches from the direct output of the pump. Might want to move the frag or the vortech again so the flow isn't directly blasting at it so close.

i completely stripped an echinata of all its flesh in a single night. gyres are powerful!!

These days circulating pumps are very powerful ( to much ) they start at 500 gph and up . You could get a fishing boat motor and put it in there LOL
I say this stuff because this past weekend I got 2 small circulation pumps 500 gph each. it was a tornado in the tank (40 gal) so much for that . Still searching for something smaller.
I just looked up the MP40 wow up to 4500 gph . A bit much so close .
Good luck with your corals .

Yea... powerful. I have it turned down to 50% but I think I’ll lower it. And I’ll move the frag. Thanks guys!
