par lighting value in the aquarium

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...

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...

My tank is a Nuvo ext Mini. Right now I mostly have Zoas, but they seem to be stretching. I'm running a Maxspect Ethereal. Concerned with the Zoas, I rented a par meter from my LFS to see how much light is actually getting to the bottom of the tank. What I found was a par of about 50 at the...

Curious if a coral is supposed to get their recommended amount of light (ex zoas at 150) for a certain period of the day or the full day? for example, having my corals gradually reach their peak (ex 150) then taper down as the day progresses or have the corals at 150 for the day with a ramp...

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...

Hello all! I just wanted to share my most recent PAR measurements I did on the stock BioCube 32g LED lights. To make it simple I made a video on it and was able to see upwards of 300 PAR under all three channels at the highest intensity of the day, using the Seneye Reef:

I have a question... I do t have a PAR meter handy, but wondering if anyone has done this yet (I’m sure someone has) I had a friend give me an AI Hydra 26, I put it over my fluval flex 32.5. The dimensions of the tank are 32”L x 15.5w x 15.65” deep. The light is 14” off the top of the water. I’m...

General background - I have a 60 gal cube, 24” all the way around 25” tall. It’s almost all LPS with a few SPS smaller drags. Sump, skimmer, fuge, 9 months old and rapidly on its way to maturity. it currently is running the AI hydra 32HD with saxbys Signature and a few mods to the intensity and...

Hey reefers looking for some advice and or opinions.....i currently have a 60 gallon standard size..... reef doing just fine with the cheap china black box lighting but i don't really like them and i know buying a better light will help much more this was the only mistake i rushed into when...

I wanted to ask those who run T5's just how high is your fixtures from the water surface and what are your PAR values as you descend into the depths? I know that PAR readings will be different with variables such as bulb type, age, and type of reflector used. However, I would think it safe to...

Hi everyone ☀️ I am installing a Kessil A360X onto a tank that is only 12” deep, 4ft long. Approximately where should the intensity be set (1%-100%)for LPS, if the light is sitting 8” above the water line? The spread is phenomenal and does a good job of lighting the entire tank. I can...

I rented an apogee 510 from a local fish store and have been using it in my display and I feel like the readings are off. My light is a single Radion gen 2 pro over a 93 gallon cube. I have had the set up for several years. I am battling high nitrate but I am lowering. My nitrate was 100 and...
