SPS base dying

[illumnae]

I recently bought a small SPS colony and placed it in a "cup/basin" area of my rock structure. The base of the SPS is not glued down, but it fits well into the "basin" with some of the lower "branches" of the colony touching the sides/base of the "basin". The rest of the colony is gaining colour (pink colour is deepening), but there is one branch near the base that is turning white. Is this because part of that branch is touching the rock so it's dying, or should I be doing something to reverse this dying process? Water parameters are fine (NO3 and PO4 undetectable).

Most of the time its insufficient flow

Thanks James! Let me try increasing my flow. I have 2x WP10 on this tank, plus a 1000L/hr HOB (holding phosguard, carbon and biosphere) and a BM Q3 all providing flow. The WP10s are only on 3 bar at the moment though (dual controller). Will increase and hope it recovers!

Lack of light for that area could be the cause too.

Dont think its lack of light. That area looks like stn. I reckon its either flow or Kh fluctuation

Definitely not light, as that colony is near the surface and directly under the light, which is about 8 inches above the surface.

Yeap Its The Flow..Suffocation Maybe..or Like everyone stated KH Flux..Or any other params
