Some of my acro frag tips white

[TORX]

Pretty sure that logic works the other way around in sorts, for every 10 bad things you read, there is 1 good one posted. Typically the same story is written on several sites about their displeasure, much like mine with JBJ. You are going to read about peoples frustrations more then there success story's. My bad product reviews get more views and responses then my positive ones.

I agree with Duke, well said. It is an adjustment period transitioning to LED. Height is not an issue, that is why there is dimming functions on LEDs. I believe our friend Mrsaltwatertank only runs is Sols at 40%. There is a video out there where he measures par and talks about the percentage.

i dont even think theres always an adjustment period, every frag i have ever got with the exception of 2 or 3 came from tanks lit with T5 or MH and i dont experience months of browning etc etc.. i do have some frags that have done f all nothing for some time.. but i doubt its lighting related.. its probably more due with the adjustment of the particular coral to life in captivity as opposed to the wild imo.

Aaron. since the beginning of time how many people have had issues keeping SPS regardless of which lighting they use? can we blame them all on lighting?? Of course not, theres many factors and key things needed to keep sps coral successfully, lighting is just one small part so why should we be able to in this case, it should be a widely accepted fact that maxspec razors can grow SPS(even if they might burn your house down) via the photos above, first hand success(derek) and reading about the success of many others online.

I was going to say what Duke had said about T5's. Many years ago when they first came out I was told t5 wouldn't keep sps and I had no problem with them. I am happy with the growth I have had in just the 4 1/2 months I have had this tank set up. I have bought frags from ChuckM Glen Brandon and Rick so I too have had frags come from all different light sources and have not had one brown out or bleach due to being fried under my LEDs. As for the Maxspect Razor Tony has I have seen in person a successful reef tank with them as the sole light source. I have also seen may pictures of successful sps tanks with the Orphek Atlantik the light I have so there is no denying LEDs won't grow an keep sps. I thought the issue in my tank could of been the temp spike due to faulty heater as all my parameters seem fine just thought I would throw it out there just in case I over looked something.

More of an adjustment period for users, not for the corals. People have to adjust to the changes as much as what is in their tanks.

Like I said above I don't know have much experience with the full spectrum LEDs but my test with my setup was pretty sound.  Everything was exactly the same (same system) and I even matched the par output and all the acros I put in the tank turned brown.

Did you have any UV led? My white LEDs are 17500k and 12000k not sure if this has any part of the success I have been having but I know a lot of white LEDs use are 6700k

I've read that PAR meters underestimate LEDs by 25%.  Not sure if that would be a factor at all, or if you corrected for that or whatever..

There are obviously lots of ways to get from point A to point B.  I've been in the hobby six years or so now and back then when getting in, Darryl set me up with T5s and at that time, most people were saying that T5s were growing SPS just fine, so I don't agree with some of what was said above.  Heck, yesterday I saw someone post on RC in the SPS section that you can't grow SPS under T5s - there are always going to be those people that post information that either is inaccurate or that is based on lack of success one way or another, but doesn't make it fact.  Some people are definitely having success with LEDs and SPS, you guys that are trying it in my opinion are obviously doing something right.  I commend you guys for even trying.  I'd be too chicken to even try.  I'd rather wait a few years until you guys have it down to a science before even contemplating it - maybe I'm not doing my part to advance the hobby! 

I think that in Tony's case, moving to T5s might simplify things a bit, as Torx sort of eluded to.  It seems like with LEDs you have to worry about covering the full spectrum and about intensity, and potentially some "hot spots", that in of itself may be too difficult for a relatively newer reefer to figure out.  I'm not saying that you can't do it with LEDs, but T5s may allow for a bit more room for error, which Tony really needs right now.  Most tanks on RC that are TOTM are T5 lit.  Is that because they are better than LEDs?  Not necessarily, but they are energy efficient, and the wide selection of bulbs allows one to tailor a specific look in terms of k.  And they grow SPS like weeds.  Its his decision obviously, and he needs to take everything that is being said and then decide what he thinks is best for him and his tank.  I'm pretty happy with my T5/LED combo, best of both worlds IMO.

I read that to Phil.  I tried to offset the numbers by about 10%.

The LED lights I use have no UV, just straight blue/white.  There was clearly an issue with just running blue/white LED's as now almost every new fixture has included a much broader range of colours.  It seems every new LED fixture that come out, has a different ratio or adds/subtracts certain colours.  I still think we are a few years away from knowing exactly what the coral needs are for LED lights. I can search the internet and find a TONNE Of threads about people having browing/colour issues with SPS and switching back to T5/MH.

I took led cause they are cheap lol.  Bulb changes don't exit for me ... Haven't thought about lighting since I added the optics.

 

[Salty Cracker]

I had brown coral until I added the UV, then I had bleached white coral.  Then the coral slowly came around to my way of thinking.  Patience + UV = success(?)

 

[DerekL]

I agree that we are still a few years away from the perfect led lighting. I spent several years researching LEDs before making my decision and buying them. Even orphek has changed the layout of the Atlantik. I don't disagree that ppl aren't having sps brown under LEDs I was just saying I haven't yet had that issue.

 

[Neopimp]

Ya my next plan is to add a string of uv and a couple more blues to the fixtures

no UV leds here(well theres 3 out of 90), just straight royal blue and 10k white, i totally dont doubt u, obviously the results you have with your tank and your experience speak for themselves, not sure what to say about those pac sun leds, you should replace them with a T5 setup and have 2 sps tanks down there in your basement.. that would be baller.

 

[Duke]

no uv's here either iirc.. no brown coral either..

I was ready to replace them, but I decided on making that tank a chalice/Acan tank ....for now.

Whose tank is this???

He's member here.. From Michigan.

didn't he have a big crash this fall?  I thought he lost a lot of sps, but maybe I'm thinking of someone else.

Yes he did.. But his tank really didn't suffer much, this is a newer photo Oct 2013
