with T5. might be the best of both worlds. I have put my Kalkwasser reactor back on line to see if that doesn't jazz up the SPS
growth as it has in the past.
Greg, don't give up on the SPS
. Like I said before, I have the ecoxotic panoramas 1 watt LEDs by 12 per module. My tank is 24" deep. I had two SPS
before switching from 48" t5 ho
X4 bulbs to LED
and I was nervous at first too. I had a green tipped colony of Pocillopora damicornis that was doing great under t5, then under the LED
started loosing some of it's green. It was still growing like crazy, then slowly I started noticing the green coming back and now it's thriving. My purple acropora turtuosa growth slowed a bit, but it's still getting bigger, and my brown acropora millepora is still about the same. I know these are not the most light demanding sps
, but that's where I wanted to start with t5's. On another note, I've noticed even faster growth with my Montipora tuberculosa and other Monti's. The only coral so far which hasn't seemed to like the LED
's or maybe had some other issue, was my new addition of green star polyps. It never opened and finally fell apart.
I do agree though, that after all the years of MH
, T5, pc
, and even regular t12 fluorescents, the best overall were the t5's. But my biggest complaint was from the t5's too, they were to bright on the eye and had no natural shimmer look. I'm want to add a couple more sps
eventually, but the wife is complaining about how much I'm spending. Even if higher light SPS
would thrive it'll be a while before I'm allowed to try...........?
