par level

Recently put an xr30 g5 blue on an AIO 24g 24x24x8. Along with this change I had a bit of a separate crash in parameters due to a shipment of unhealthy corals and nems but even before my parameters went out of whack it seemed that going ab+ at more than 20 percent was causing polyps to recede...

Hi all! I have a Landen 26g AIO and I recently added IM custom media caddy fuge in the middle chamber which almost fits perfectly. I have a copepod hotel/motel/holiday inn ;) on the bottom rack and above it have a ball of chaeto powered for 12 hours by a JBJ 4W white light. It was growing...

Okay, I am new to the whole PAR reader rabbit hole and trying to map out my tanks and plan out future corals. Looking for some help to find out where I am messing up with my par results. I got a $150 par reader off amazon and was so stoked about it but now I am so confused because my readings...

Hi Everyone! TLDR: Enjoy this Reef lighting DLI made simple calculator I made to make choosing your lighting settings easier. Target DLI over SPS of 10.5 (7-12.5 range) DLI, and Target DLI over LPS of 5 (2-7 range) DLI. So I went down the PAR & DLI rabbit hole because I haven't been 100% happy...

Purchased new about a year ago. Used once and has been in storage since. Excellent condition, nearly new and works great.

Hello! I’m seeking for some help regarding PAR values for gorgonians. I’ve been measuring the PAR in my tank with the Photone app and a diffuser. I have 2 AI PRIME set at maximum height on the rigid bracket and are using the Stuart Bertram schedule at 100% These are the PAR readings If...

This is the 510 model that measures LED . It’s Two year old with 39 inch fiberglass apogee wand not the knock off . I have used it may be five times over the years call. Perfect condition just like new.

New to having a reef tank at a little over one month in, tank fully cycled, and have some Zoas and one Rhodactis Mushroom coral already. I have some important compatibility, PAR, and placement questions namely about Acans/Micromussa, Blastos, and more, that are probably all very basic questions...

Hello, Has anyone figured out the best settings for PAR and coloration on the above for a mixed tank? The Lagoon style is only 12" deep and the G6's seem very powerful.

Hi all, I’ve been looking at upgrading my lights. I currently have a kessil A80 Tuna blue. Would the xr15 pro gen 4 be much of an upgrade? And does it still hold up in 2023?

Just curious if anyone has used photone or another cheaper lux/par meter to measure the par of an LED and T5 combo. I am about to add two t5 bulbs to supplement my two kessil leds on my tank and i’m not sure how that process would work. Seems like the kelvin of ATI T5’s are higher than any...

T5 hybrid with A360WE Kessil. I tested a couple heights and intensity settings. I do not have ability to ramp up or down. What I was guessing was to do two hours of Kessil at 75% and then T5 comes on for 4 hours with both and then the Kessil alone for 2 hours. What are your thoughts.

getting out of the hobby so selling my par meter, i dont have a actual pic at the moment but i added a stock pic from brs, it plugs into your computer, it comes with the wand, $200 shipped, paypal only, text for more info 251-472-5002 and ill get some actual pics up later, thanks

Future tank will be 6'Lx28"Wx26"H. I'm tall so figured I'd add 2" in height and hopefully still be able to reach the bottom. I know three XR30 G6 blue's will be enough to light this tank for SPS. However I wanted to add two 60" reefbrites blues, 1 on each side and maybe angled in a little to...

Hey everyone. I just recently got an AI Prime 16 and tested the PAR on it today. It was a headache trying to research what kind of schedule I should go off of. I ended up sort of mimicking the schedule recommended by BRS. I found the PAR levels they recommended too high for my LPS dominant...

What type of coral would be happiest/safest going on the arch of the rock? Currently none of my coral are glued down because I wanted to make sure that they will thrive in their location before it becomes their permanent home. There are plenty of spaces on the main sections of the rock...

First off who has BTA’s and what are your favorite lights that have helped them thrive for 2+ years(obviously I want longer but some people haven’t been in the hobby for 5+ years…) 2. what should I be looking for in a light? Is Par really everything? Controllability?(honestly would like to set...

Hello fellow saltines, My tank is a small 5g (16"L x 8"D x 11"H). This is my first tank. No corals yet because the tank is only 1 month old but I'm planning to add some down the road. The stock light most likely won't won't because the tank was made for freshwater so I'm thinking of getting the...

I recently saw a post on PAR and how important it can be "IF" you understand it...so I've been doing a little (very little) search on the subject and ...wow that is a Pandoras box ! I currently have a 25 nano and a 55g (currently cycling) both are running radions...I would like to know a...

Hey guys, Last year I bought two XR15 Pro fixtures and I'm really happy with them. My Acros on the top are starting to shadow themselves and so I ordered another fixture. Tank: RedSea Reefer 425XL (Mixed-reef) Currently running the two fixtures at 90% intensity. (and the fans sometimes do get...

Hello everyone, I'm trying to plan my first LPS dominant system and I've been doing researching on corals, especially when it comes to par measurements. I saw the these two company give par recommendations for all their corals, but they couldn't be any more different. Has anyone used either of...
