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...

We invite you all to talk about LIGHT. Come share your knowledge, your thoughts and experience with us! original source link : https://orphek.com/lighting-the-reef-aquarium/ By Dana Riddle There are many aspects involved in successfully husbandry of a reef aquarium, not the least of which is...

Hey Reefers- I currently have an XR-30 Gen4 pro over my 25 gallon lagoon (mixed reef). I am using the RMS mount, which puts the fixture at about 8.5 inches above the water line. My tank dimensions are : (24" x 20" x 12") I have been using a modified SPS AB+ template at 30% maximum intensity...

I’ve been trying to get some input on the current USA marine orbit led light There is 3 different versions of them atm The regular The ic The ic pro I currently have the regular on a 10 gallon tank about 2 inches off the surface how much power is this thing really

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...

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...

Please help!!! I cant decide between 2 Atlantik V4 Orphek lights or 3 gen4 pros with a coralife t5. This is going to kight an sps dominant 165gallon tank. 72wide 20 deep 26 tall. Opinions and comparisons would help out alot. I like the idea of the radions programming and the t5, I have also seen...

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...

Hello Reefers- I really need some solid advice on lighting settings for my RSR 250. It is a mixed reef with mostly LPS and a few acros. I currently have 2x Kessil A360's peaking at 90% intensity for 3 hours, then 75% for another 3 hours. Ramp up/down time is about 2 hours. The tank is...

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...

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...

so i am setting up a new tank, i will be getting a par meter and most likely the PMK. questions i have are as follows: 1. does anyone really need to leave the PAR meter in the tank 24/7? 2. if you do leave it in tank can you have multiple? or more over why would you? 3. if i am buying a high...

How many of us truly understand the importance of these measurements within lighting and our reef tanks? I produced a video 'hoping' to help those who dont quite understand it! - Hope you enjoy it :)

Hello reefers! I am brand new to R2r. My new Red Sea Reefer 250 is being delivered on Tuesday to replace my 28g nanocube and I couldn't be more excited. I've finally decided to go with 2 x Kessil A160WE's to light my reef tank. I plan on keeping soft coral, LPS, and some less demanding SPS...

I need to borrow a par meter. i could trade some coral to whoever has one that i could borrow for a day

So I have a cheap (relative to other lights in this hobby) fluval reef 2.0 led and I've had a hard time keeping anything but softies and feel like I want to see about making a change to the lighting schedule or just swapping to a pair of used generic black boxes I got cheap. I really want to see...

OK, So I have my new PAR meter coming tomorrow and I was wondering where my PAR should be? My tank is a 300 US Gallon 48 x 48 x 30. I want to start keeping LPS/SPS and Softies. I have 4 Rapid LED Oynx fixtures that are dimmable and they are controlled by my Apex, so I do ramp them up and down...

Post up ones with the most noticeable growth, color and polyp extensions . & If you have the PAR to go along with your schedule, please do share. Thanks ! . . . Anddd Go !

What PAR does everyone keep their Magnificent nems at?

I'd like to start a discussion based on a few things I've been reading lately regarding optimum daily light integral, PAR and photosaturation in our reef tanks and with the advent of this new lighting forum. For those of you with PAR meters and the ability to continually monitor PAR via an...

First time here..... Hellow R2R I was wondering what are ideal Par values/numbers at top, mid & bottom for a mixed reef to include softies, LPS & SPS. All this Par, light intensity & color talk is confusing to me. :) I would like advice & recommendations on a 12 hr lighting schedule from dusk...

I've never had luck with Red Planet frags, but I traded some hammer and acro corals for a large piece of Red Planet and am trying again. I figure a larger colony will have a better chance of survival. Parameters: Ca - 450 Alk - 7.3 Mg - 1290 PO4 -.04 NO3 - 0-5 I've had the red planet about...

I did my research and found that with the placement in my tank from the surface and the PAR readings of my light (Current USA orbit marine), the frogspawn would receive anywhere from 80-100 PAR. Is there anyone who has tried this (or any other euphyllia corals) with the same light setup?
