Where did you get the FM Ultra Blue from? I cannot find them here.
Also given you dim the T5s how long do your bulbs last?
I have been following your suggestion of turning off LEDs when T5s on but my LEDs in the pm are at higher power (70%) then dim down over 3 hours. Have not seen much difference in coral colors yet but I did have a bit of an alk swing from my ca-reactor not working right so that could be it.
And anemone in a reef tank! Or is that a torch?
I had to buy the bulbs direct from Germany, but they arrived in the US in 4 days with no extra charge so I consider them a bargain. Honestly though I must disagree with Lunar. I feel they are slightly less blue than the ATI Blue Plus, and I say that with me running the two bulbs side by side.
As to the dimming, yes 100% I think the dimming is reducing the useful life on my bulbs. I recently changed out my Giesemann Super Actinics for new ATI Blue Plus because I felt that after just 4 months they were putting out too little PAR to be useful. My plan is to replace all the bulbs every six months.
No one ever said Reefin' was cheap!!
