I just got 2 small ricordea mushrooms and 1 small umbrella. on this site it says they need medium light. I have a 250w MH HQI pendant over my tank, where should I place them, lower, middle or upper regions of the rock structure??
With the ricordea... upper, middle, lower would all work but block the direct MH lighting. Place it under a ledge in the rocks and they should grow like crazy.
