refugium lighting

[markthereefman]

i have bought a 150w metal halide for my refugeium but the new bulb taht came with it is an unknown colour temperature.
is this crucial for a refugium as i have encounterd an algae bloom.

Well,
Is this algae bloom limited to your refugium or has it traveled to your main tank?
I have not really been concerned with the color temperature of my refugium lighting mainly because I wanted good macro algae growth and the lower the kelvin temp the better it seems to grow. I am using a couple of fluorescent grow bulbs because I thought metal halide would be overkill??
Do you filter your refugium water before you pump it back to your main tank?

yes once the water from refugium travells to the next bin it meets a turboflotor 1000 and uv steriliser.
within the skimmer wet and dry chamber is seachem purigen .
water is returned at this point.
