I really, really feel sorry for people in this forum that ask questions about coral growth and *still* get fed piles of FUD from anti-LED zealots that really need to stop spreading disinformation. Especially T5 owners. Given the discussions in the SPS forums about the success of those tanks under LEDs it's kind of nauseating we have to hear this in this forum.
Fernalfer, I can grow a paly colony, *ANY* paly colony to the size of a grapefruit in less than a year by controlling nutrients, and when I switched to LEDs from over priced shoplights (T5s ) my growth accelerated. When Palys or Zoas stretch it's because they want more light and are in a low nutrient situation.
Also, because you have a young tank Ammonia to Nitrate conversion isn't established yet. I see zoas and palys get 'stalky' like this a lot in young tanks. Once the bio filter is up to snuff they get more nutrients. High iodine amounts will also cause zoas and palys to became 'stalky'.
Turn your lights up, or move the zoas up. I don't want you to increase feeding because it's a young tank and you may be setting yourself up for issues down the road. Last, don't listen to somebody telling you to sell your LEDs and buy T5's because LED's can't grow zoas. That's beyond dumb.
:facepalm:
Let me know after couple of years...
Well, unless you don't know any better anyway... :thumbdown
All my friends that know what they're doing went back to T5s or MHs.
Unless they had spend that fortune and they are too proud. :hammer:
My current tank is only about 9 years+ old with T5s.
The system I set up for the LEDs went to T5s after a year.
Huge difference in many aspects.
Not only me...
Try search deep and you'll find serious people in this forum and all ver the world that will tell you the same.
I'm not here to let you down nor to tell people to do wrong.
I actually telling people what they need to hear.
LEDs are a good selling tool for the newbies that don't know any better.
Plus... they won't save you THAT much money on electricity... Did you know that?
Not worthy.
But everyone says what they want, right?
Well, I tell you what I want to tell you... :hmm4:
Go T5s and be happy!!
Everyone has their choices and of course I respect that too.
It just doesn't make sense to keep LEDs and not to go T5s because those LEDs were a fortune. Just sell them and get a T5 fixture.
You can actually keep zoas and corals ALIVE for years with NO fluorescents, but the HO T5s are much better. LEDs will keep they Alive, but not better then T5s in the long run. Period.
Guess what my friend, they have more LEDs running in shops nowadays then T5s.
LEDs are actually stoplights!!!!!!
