good info .

[reefer guy]

Good technical infos but what I would be more interested to SEE is the end result; I am not sold out to the idea of led for sps tanks as an equally or better replacement for halides. I have been reading and searching for threads (here and reef central) that shows success in keeping sps under led and all I can come up with is terms as "holding colors", "thriving", "surviving" What I want to see is results crazy colorations,rapid growth and flourishing successes which in my years of keeping sps under halides has been a living testimony not only to me but to other reefers alike.

Perhaps the only way to compare halides and led is to get two frags from a colony, under same water yet isolated from each other and wait for a year. This is a comparison which I believe is justifiable than just simply comparing pars. Only then will I put my hats off to led.

The reefer's David00061 @ RC has been having great results with his reef tank.....

seen it before. it is having great results alright. his thread, http://www.reefcentr...2062544&page=28 (check on post #692) his monti has good growth rate compared to your link 7 months later ( although the other sps, which seems like a milli to me, right beside it exhibited less growth.) and to take note, on the above link, corals have been encrusted already when he placed in tank, which means it was not totally grown out from an led tank.

now i wonder if he uses halides, how good could it be. here is my monti growth under halides for 2.5 months https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-ash4/316681_10150474109394148_725304287_n.jpg

still, I want to see end results for growth and coloration, then we can start comparing halides and leds. I don't see any point on this just by comparing technical infos and conclude one is better than the other.

Besides lighting, there are a few considerations like KH stability, pH, NO2.....etc. Since your corals (SPS, LPS) are so healthy, colored and rapid growth under MH, which meant your water perimeters is perfectly good so why not you switch to LED and try up for 6 months. The result from you will definitely benefit to those who are so skeptical on the SPS using current LED technology.

as i have quoted on my first post in this thread, i am not sold out to the idea of led lights on sps tank. and why do you think i would fix something that is not broken in my system? since you are promoting LED is better than halides, why not show us the fruits of your led tank instead?

chill bro and don't be too worked out, not trying to get into arguments but seriously, halides vs. led? there is totally no comparison. as you have mentioned, other water parameters affect growth and colouration, so the best way to compare as i previously mentioned is under same water yet isolated. until such justified comparison is produced i won't buy the idea of led for sps. VIvi Aquariums is marketing led lights for reefers, I would have done the same thing if i am in this business.

you should know by now that i have been reading and searching answers for led lights for sps tanks; for obvious reasons, i would want to venture in something less costly in the long run. but as of date, i find led has not reached what halides can achieve for the hobbyists; it will definitely sooner or later but not now. so till the time it has been proven by the majority of sps reefers, i'd stick to halides.

bottomline; Vivid aquarium has not convinced me of a justified comparison other than the technology led carries, and the products they carry

cheers!

Hi bro,

I'm not here to promoting LED better than MH or vice visa or convince you into LED lighting but just to share the interesting LED finding on the web that I came across. As I'm not LED supplier, seller nor distributor so whether you are buying the idea of LED thingy or not is not my concern so no point of me arguing with you too .

Reefing is just a hobby and everyone has his/her own preference, It's good that you know what your needs and happy with your MH performance !

Cheer:) !

here is a partial shot of my tank after 6-7 months under the Illumina. It was previously under 2x 250 HQI +2x T5. No problem growing corals and they look better than they ever did. Mind you, good water parameters do play a role, as well as water movement.

Great looking sps under LEDs
