  • 15K XM 400w

    I've been using the new 15K XM 400w SE bulbs for over 150+hours and so far I don't like it due to Acros loosing their colors. Has anyone had this similar experience with this exact bulb?

          The PAR/PPFD on this bulb is terrible. If I remember right, the 20K even had better stats than the 15K! Check Sanjay's or JBNY's websites, they performed pretty poorly. OTOH, I have a friend who runs them and her SPS look great, but it's a shallow tank so 400W even with the low PAR is enough.

            I also used one for about a week, didn't like the color or the intensity. And after seeing the stats from sanjay's article, I can see why. 10k's were too yellow for my taste. Currently using the Hamiltons and will let them run their course, I will probably replace with aquaconnects. Couldn't afford them after buying the 3 ballasts (PFO HQI) and 3 Lumenarcs.

                Are you using those 20k XM bulbs with the Zeovit method? What are your results like compared to people who use 10k on the Zeovit Method?

                  I hate 10k so that is not an option for me.. Here is a link to my gallery so you can see how my corals look under 20k off SLS m59 ballasts..

                    Hey Jeff, I noticed you had a Sohal tang in your tank. How does he get along with the others? I have heard they are pretty aggressive. Been wanting to get one to finish off my fish list.

                        TY, Its a standard 240 8*2*2. The sohol is about 4" long and does well with others. I have a 4.5" regal that keeps him inline. I have had the regal 6.5 yrs and he came form my old 90 gallon. They all do surprisingly well together.. They bicker now and then but nothing major. I am hoping her stays as peaceful as he is now thats for sure. Hes a GORGEOUS fish.. Oh yea I need some new full tank shots those are pretty old..

                          I had the opportunity for a 300, 96x30x24 when I bought my 225 but couldn't talk the wife into letting me redirect the staircase to fit it in the allotted space. Sure do miss that extra 2 feet.
