oh creennnndooonnnn. i need your addresssssss. can i bring you beer as payment?

Moede = victoly. i'll be on my way as soon as I get your address.

Dare I say they are becoming/have become the premier reef store in town. In my humble opinion anyway. Well done Hunter/Gary/AD crew. It's not just because my office is 3 blocks from your store, i swear....

Love me some AD.

Low is very low. It's happiest when my tank is in feed mode with all pumps off. Sent from my iPhone using Tapatalk

Chris, yeah it's happy in my cube in the back left, where the return pump flows above it but doesn't touch it. Sent from my iPhone using Tapatalk

He got the frag from me. I'm serious when I say it needs *low* flow. Sent from my iPhone using Tapatalk

Low-medium for all of those will be bueno. And to clarify, all of your LEDs are royal blue ? Sent from my iPhone using Tapatalk

I hope they all win. I like having options. I've seen quite a few of them come and go in my short existence on this planet. Perhaps we need a nostalgia thread...

I'm not sure man, I got them from Tim (wizardx322) this weekend. I'll have to ask him. They're my first stick SPS, so I'm a wee bit nervous...

Thanks, got it from KimP. I really like it as well. I need to frag it though, it's outgrowing it's rock.

It's my favorite piece. I got it from Tim (wizardx322) this weekend. His tank is stellar! I'm still learning about the cyphastrea variants, and I'm not 100% sold that this is meteor shower, but I sure do like it regardless.

Time for the tank hardware: Apex Apex WXM (mp10 control) DIY 24 LED from RapidLED (12 RB, 12CW @ 0.7 amps each channel, 2 Meanwell 48Ds controlled by the Apex. I currently ramp the Blues/Whites up and down for about an hour with an 8 hour photoperiod. Blues are at 60%, whites are at 30%). Ecotech MP10 (40% reefcrest most of the day, several Nutrient Expos at 10 minute intervals and calmed down to 10% constant at night) Tunze 9002 Skimmer with intank cup (not crazy about this skimmer, I can only manage a wet skim) Intank Media basket with carbon/purigen, mechanical filtration is taken care of by 2 different filter sponge media. Cobalt MJ1200 w/ y split locline on return Autotopoff.com ATO Ebo 300w heater controlled by Apex Linksys WRT54G with DDWRT to take care of apex networking duties Livestock list to come.

Per the admins, we should probably just let this conversation die. Everyone has an opinion, and people can vote with their dollars if they so choose. May the best reef store win.

I am not familiar with your meter and I do not understand a need for a correction factor in the actinic range. This should be a function of internal programing during initial calibration of the meter at the manufacture. However, if you use the same meter to make both measurements it does not matter what the correction factor is because it is the same correction factor in both cases. Patrick Email from Apogee Instruments on Measuring LED with Quantum Sensor: "In regards to measuring LEDs with our quantum sensor, there are some caveats to doing so. The following link shows the spectral response of our quantum sensor (http://www.apogeeinstruments.com/quantum/spectralresponse.html). As the graph shows, Apogee quantum sensors underweight blue light, and as a result, photon flux measurements for blue LEDs will be too low. They also overweight red light up to a wavelength of approximately 650 nm, above which they do not measure, and as a result, photon flux measurement for red LEDs will either be too high (if the LED output is all below 650 nm) or too low (if a non-negligible fraction of the LED output is above 650 nm). Additionally, LEDs often have a very narrow spectral output, with a sharp peak of only a few nanometers. So, unless the quantum sensor has a perfectly flat spectral response, meaning it weights all wavelengths of light exactly the same, there will be errors. Electrically calibrated Apogee quantum sensors will likely provide a reasonable measurement for white LEDs because they are broadband, and because electrically calibrated quantum sensors are calibrated under CWF lamps. However, for narrowband LEDs, like red and blue, Apogee quantum sensors will not provide an accurate measurement. As a less accurate method you can use the same spectral response graph as mentioned above to get a relative idea of the error. For example, a 450nm blue LED will have a relative response of approximately 0.8. Therefore, you can figure that the photon flux reading from the sensor is reading approximately 20% low. Just remember, this approach is only relative so give yourself a wide margin of potential error. A blue/white configuration should give you reasonable accuracy, particularly from the broadband spectrum of the white.

From the horse's mouth: http://www.apogeeinstruments.com/quantum/spectralresponse.html " An ideal quantum sensor would give equal emphasis to all photons between 400 and 700 nm and would exclude photons above and below these wavelengths. The response of such a sensor is shown in the adjacent graph. The most accurate way to measure this radiation is with our spectroradiometer, which costs less than $4000. Our Quantum Meters are accurate to within about ±3 percent for common light sources. The spectral response of the Apogee Sensor used in Quantum Meters and the Quantum Sensor is shown at right. As the figure indicates, the sensor underestimates the 400 to 500 nm wavelengths (blue light), overestimates the 550-650 wavelengths (yellow and orange light), and has little sensitivity above 650 nm (red light). Fortunately, common light sources are mixtures of colors and the spectral errors offset each other. The sensor measures green light (500-550 nm) accurately, so it can be used to measure the radiation inside and at the bottom of plant canopies."

Here it is. Was feeling particularly proud of it, so I took a picture. Tank details to follow when I'm at a keyboard instead of a phone. Sent from my iPhone using Tapatalk

Something to note is that it is primarily *blue* LEDs that are underrepresented. Apogee says by ~20%

Just stunning. Well done sir. Sent from my iPhone using Tapatalk
