Clams and shrooms?

[Old Guy]

The pic shown is with the 250w SA 14000k and 2 95 watt VHO. 1 white, 1 actinic. The srooms that are directly under the MH, stay smaller and don't try too hard to grow up the rock. The ones down farther in the tank expand to about 5". Very little par with the SA bulb IMO and got humugus sroom growth. I have since changed out the 14000k for a 10000k AB with 2 actinic's. Huge difference. Srooms stay even smaller on top which in turn lets my zoo's spread out .
