do you guys think my 150 watt Mh with 15000k bulb would provide enough light to keep a clam? also i was wondering if it was enough for anemones and other light seeking inverts?
Depends on the clam, the higher light species would have to go toward the top of the tank, you could probably keep most anemones. What size tank is that?? Mines a 65gallon 36x18x24
