    Beyond PAR - DLI in the Reef Aquarium

    We measure light we used to grow coral with PAR (Photosynthetically active radiation) But have you ever considered Par vs the duration of your lighting schedule? For example 200 Par for 5 hours in one tank is completely different from 200 par over 10h in another tank. Thats over double the...

    Orange Setosa (Montipora) PSA!!

    Background Classification All of the hard corals fall under the order, Scleractinia, which falls under the subclass Hexacorallia. Hexacorallia is under the class, Anthozoa, within the phylum, Cnidaria. So, when we talk about SPS coral, some people say, "small polyp stony" coral, while others...

    Test the AI Hydra 52 HD?!

    As mentioned in another thread, I’d really like BRS to do their standard evaluation & dive into the AI Hydra 52 HD. It’s their flagship model, doesn’t spread light the same way as the 26 HD, and is worth reviewing (with PAR mapping) as they’ve been around a relatively long time, you sell them...

    Calculating par on ai hydra 26

    Does anyone know how to calculate or even guess par readings based on ai hydra 26 settings? I have 2 hydras on a 40b 16” deep reef and plan on using the ab+ spectrum. I don’t have any access to a par meter but I feel like there should be some sort of calculation out there for something like...

    Rented Par Meter, needs suggestions.

    I just renter a PAR meter from BRS for$50/2 weeks. Anyways, I'm wanting to make my tank a mixed reef tank. So far I have mainly LPS and Zoas (2 Acros that haven't done much). Which is why I wanted to rent a PAR meter to fine tune things before really diving into and buying some good SPS. My...

    Kessil LEDs, Intensity and PAR

    I am admittedly new to the whole question of measuring PAR. I have a 150 (36" tall) tank with three Kessil 360's on it that I bought used. I was told that the Kessil's would be "good for any type of coral that (I) want to keep." I have made the usual beginner mistakes with over-feeding, working...

    If no one agrees on PAR levels...

    I borrowed a PAR meter, measured various spots in my tank, and hit the Google to determine if I need to tweak my intensity. I also tried to search this forum. BUT It looks like there is little agreement on appropriate PAR levels. I'd love to see a chart with "low light is xxx-yyy PAR" or LPS...

    PAR and time

    I am next on the list to borrow my local club's PAR meter :D and I starting thinking - different people run their lights for different lengths of time. It seems to me that the amount of light and the duration of the light both combine for a total PAR/day value. For example: if I run low PAR...

    Lighting Output

    I thought it would be worth noting a lighting change I made recently. In my Nuvo 40, I had been using a Masxpect Ethereal for lighting with the thought that the output it produced would be more than sufficient for a mixed reef in a tank that size. I will admit that I like my lighting to look a...

    New Zoa's... Should I Dim The Lights

    I have a big spread of Zoas coming in tomorrow for my Zoa dominant tank (currently without coral). They are going into a MAX-E 170 with Hydra 26s. The seller I am buying from says that they are coming from tanks with 90-200 par (depending on distance from light). My tank is mostly 80-240 par (to...

    1x Kessil A360WE over a Red Sea Reefer 250?

    Hello Reefers! What is your opinion on having 1x Kessil a360WE over a Red Sea Reefer 250 (35.5 inches long). I know most reefers recommend 2x 360's over this particular tank, but I'am getting excellent coverage with a single 360 and no perceivable shadowing. I only have soft coral and LPS in...
