That would be your primary reason for the shrooms not doing so well. Until you get the MH, place the shrooms as high on the rock as possible but not in any heavy water flow. Once the MH is in place be sure all the corals are placed close to or on the substrate and "light acclimate" the tank to the new intensity.Thumper said:The lighting is questionable at this point with only a little over 200 watts but the lfs told me that the shrooms didnt need much light. New lights have been ordered last week to help that end with 3 250 watt 12,000k MH.
