Who's running 400 watt lamps w/luminarc reflictors over your sps systems, and what bulbs are you using.

SunnyX,
How far from the water you have your bulbs ? Mine right now are at 10" but I'm thinking if I should lower them a bit.
An off topic for you...... how do you avoid your sand clumping ? I have the same substrate and I'm having problems.

On a 400 HQI ballast try the Helios 20K bulb,
super bright, great color and they should last longer than the Radiums.

I am looking to get the Sfiligoi XR4 400W myself. I don't think you should bother trying out the AC14K... Don't get me wrong, this bulb is probably one of the best bulbs out there in terms of brightness/fluorescence but this is on an HQI ballast. The Sfiligoi comes with a magnetic ballast. On such a ballast the XM 20K has more PAR than the AC14K.
