I would say for that LPS tank its probably more than enough - scoly do just fine in 100 - 150 par. A cheepo 4 bulb fixture would have taken care of it lol.
hi i just installed my ati powermodule beside my giesemann, the ati was abit overkill imo, i was tweaking it abit just now and realized that the powermodule does not have its own app. so i think the giesemann is a tad bit more user friendly! here is a pic of both lights
haha if you would wait a few more weeks, i can tell you which one is better! so far, zoanthids have been growing really fast under my giesemann lighting as compared to my old ai prime hd. so if ur aiming for growth, t5 is the way to go! but the powermodule is a really nice looking light though! even the led itself is enough to light up all of my tank!
Ya, Ive a couple of ATI fixtures and they really are par monsters. I don't know if its the ballast or reflectors or some kinds magic but they are hard to beat. I use MH / T5s and LEDs on different tanks. So what did I order for a new Reefer 750 build at my office? 8 x 80 Powermodule Hybred - couldn't help myself. Actually I dam near order a Spectra (run one at home) but thought the MHs would blind everyone as I run them about 18" over the tank as opposed to 10-12 for LEDs. Giesemann builds such beautiful stuff though and I have a friend with the Matrix II on a SPS tank absolutely packed from 2 year old nubs that I'm sure it produces enough par for any application.
if you do go with the giesemann all t5 then it wont show as much color as the led, even if yoj install 4 blue bulbs. [emoji1] giesemann aurora is a hybrid if im not mistaken, maybe try that? overall i would say the giesemann has given me lots of coral growth and im very happy with it, although i wouldnt be able to see the coloration of what an led would give .
