XM 250W 20K SE MH anyone using them?

[lazyreefer]

Hey guys question,

I used to use XM 10K SE 250W only with PFO refelectors on my 29 gallon AGA tank (bright as hell). But I wanted to have more blue look so I bought a XM 250W 20K to replace the 10K. The zoo's look amazing under this light but it is so dim compared to the 10K. I plan to get some sps in the future and I was wondering would the 20K be enough? will my zoos act neg because of lower intensity light? The bulb is about 9 inches off the water.

TIA

Regardless that's still a lot of light over a 29 gallon tank. If you don't want the bulb to look as "dim" go with something like a 14K bulb, it should give you a nice color overall for the tank. You should still be more than fine to keep SPS, but as it's come to my attention there's a lot more to growing SPS than just the lighting.

Just worried because the par value for the xm 20K was less than half compared to 10K.

250w 20k, 14k, or any K is good enough on a 29gal

lazyreefer, I would be more worried about keeping temp, alk, cal, mag, nitrate, and phosphate stable at acceptable levels . Lighting will be your least challange.
