Ok.. I have another (possibly stupid) question regarding lighting... What is the difference in double ended Metal Halides and the regular socket type Metal Halides ? Are there other types ??? (as you can tell I am not sure about this stuff). Which is better for a reef tank ?
The reason is that I am looking at upgrading my lighting and the one that looks good is the "3' PROTOSTAR 250 WATT 10,000K HQI & FLUORESCENT 95W VHO" from Hamilton Tech. (
http://www.hamiltontechnology.com/sh...amp;cat=3&). This looks good as it has that dawn to dusk ballast.
Or should I just get a regular Metal Halide from say PFO Lighting. Are there others that are cheaper ?
It seems that both use different types of Metal Halide. Which one is preferred for a reef tank?
Another question is... based on my current tank (35 GAL), is a single MH with dual PC/VHO actinics good enough or should I opt for the dual MH with dual PC/VHO actinics ? Tank dimensions are 36" x 12" x 16".
Last question... do ALL Metal Halide fixtures have that dawn to dusk effect (I'm assuming this means that the MH will slowly decrease/increase in intensity when turned off/on). If not, what specific type of ballast should I look for.
Thanks..
MS
