I have just switched out the 2 x 400W halides and 4 x T5 and gone back to my Giesemann Matrix II that I had sitting around to see if I can save some money on electricity. Some of the LPS were looking a bit sorry for them selves (I suspect par of 600 plus would do that). Now par levels around the 100-150 mark.
Globe selection is 2 x pure actinic / 2 x blue plus. Tried the Coral plus and purple plus but it washed out the tank IMO. I also have a small Tunze blue LED light running which runs from 10AM to 9PM.
Anyway here are some pics with the T5 and LED running.



Thanks for looking.
