Tank Pics Switched to LEDs growth pics

So the apogee 200 which is the one I believe the club and myself own.. There are multiple articles and even Apogee's own site stating that the 200 requires an adjustment to the readings for it to be considered close to accurate.. Apogee just released an upgrade to the MP500 from the 200... According to them this sensor is much better and also supports all forms of light. Seems like from what i have read the white light measures more accurate and blue light is where the issue is. Here are a few articles.. The first is a comparison of on Apogee's site of the two different sensors...

Aquarium Par Meters - Apogee Instruments

Here is an article from Apogee on how they calibrate the MQ200 sensor.. They also include a table for error correction..

Light Intensity Measurements for Light Emitting Diodes (LEDs); Correcting for errors

Here is an article of how other hobbyist have adapted their readings.

This is the article that I really found interesting.. Reefbuilder uses both meters to compare the results..

Last one for your bathroom reading This article is Reefbuilder introducing the new MQ500 sensor..

Thanks.. I am looking to upgrade mine in the future.. I will take readings before and then send it off to be upgraded..

 

How's everything looking? I know Hart had a kick *** tank with hydra 26s on it. I never saw it in person but the pics were amazing. Just curious to see a reef breeder lit sps dominant tank.

 

Jeremy - here is a reefbreeder lit SPS dominant tank. These are the value fixtures.

 

Bill and dave. How many lights are you running? BTW both your tanks are looking great.

 

Thanks! We have 6 value fixtures over our 210 (tank above) and 4 photon 32's over our 280.

 

That's too bad Bill. LEDs are stronger than people expect and without gradually increasing output many have lost specimens. May not be the issue but LEDs are your only recent change.

Been there done that!
I'm an extremely lazy reefer so the simplicity of halides worx to well
I also experienced rtn and lost many sps.
But on a good note,a few did come back after switching out fixtures.

Hope you get it to stop and turn thing around. DAMN! That sucks.

 

Can't go wrong with t5. Plug them in and watch everything grow. Then you will have to fiddle with bulb combos lol. Like I did till I found one I liked.

 

When i went from mh to leds I had to start from about 10% and it took a good 4 months to be able to turn the lights up without things paling out. I have found though too that the wide angle 120's are much preferable to the 80/90's.. They're like freakin lazer beams.. That and having to feed a lot more were the noteworthy lessons I learned. I did lose an sps frag shortly after the 4 months because I moved it about an inch towards the center of the light and an inch or so up, went clear and melted within 14 hours or so..
Hopefully youre stuff will pull through.

 

I'd have to agree with some of the previous posts. I currently have my kessils at 100% during a short period of time during the day and it took me a long while to get them there. Without digging out the laptop I'm also pretty sure that my par numbers are about half of what you have. I freaked at first when I saw they were so low....but after a lot of reading I came to the conclusion that leds have a lot lower par value than other lights due to the fact that they don't show up on the scale. Inot fact bulk reef in one of their videos says that par values shouldn't even be considered or even something you should worry about. I think 4 fixtures may be a lot for the tank and %levels may be a little high out the gate. I'm guessing the corals are in complete shock. I understand if you don't want to do it again given your experience and the collection we all know you possess...but if you do if recommend taking it slower and lover. I've seen the growth on many tanks...so it can obviously be done...just not quite as foolproof as the "older" stuff. Trust me I know...I was in the same boat you are in now last year the whole led game is/was new to me. Good luck/ hope everything makes it ok.
