I have 2 150w MHs,
I sure want some of those
problem is that the guy at lfs told me the clams need at least 8hrs of MHs.
That's way too much light.
My tank will be a hair algae farm if I leave MHs on that long.
Right now, have a reef fish mixed tank, but will mainly go with reef.
And I set MHs on only 4 hrs a day
And my corals are doing so well,
best of all, I dont' have hair algae!!
How long do you leave your light on?
Those clams are pretty.
