par

I just downloaded the Photone app so I don’t have to buy an expensive par meter, only to use it a couple times in a month, but I don’t completely trust the results. I was wondering if there is anybody in south jersey, or around south jersey, that is willing to lend me their par meter, or sell to...

I recently switched from a Kessil a360x + Reef Brite combo to a Ecotech Radion XR15G6. I wanted a more streamlined fixture and the Kessil shimmer was irritating my migraines. I debated about getting the XR30, but I want a mixed reef and told myself the 15 would be adequate if I kept the SPS at...

So what i have noticed whenever i place a small bag of activated carbon in my 100 gallon some zoas ( not all) and some other corals seem to close up a bit. The reason i place the carbon in the first place is to clear up the yellow pinkments in the water. I have read that activated carbon removes...

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...

I need some lighting pointers after being out of the loop for 5 years or so. We've moved from a 40B (16" height) Now setup a 120g Eurobraced Peninsula Current lighting consists of the following. 4 Kessil A150's, 10k Sky Blue color temp 10am to about 11:30am natural sunlight through high bay...

My PAR is 109 at the pick on SPS level. I want to safely increase it and have a hard time to find the video. I been told that i can use acclimation for it, but it takes the light down. if i need to set the schedule higher and use acclimation right after, what is % i should use on the acclimation...

I'm a complete newbie trying to do it right the first time. I have a 90cm 40watt mariglo light over a 160L rectangular tank and I'm wondering how high it should be to roughly optimise par levels. I have live rock that is relatively close to the ground spanning from one side to the other. Any...

Hi all, My tank is 2ft deep with around 125-140PAR at the sandbed; I have a couple spots I'm looking at. I'm looking for suggestions for corals than would do well down there. I'll most likely put them on a little standalone liverock "island". The flow is pretty high in one location and...

Hi can anyone give me up to date information on lighting par levels for Gonipora… Information I’ve been finding is old….. Want actual numerical values please and not just low to medium lighting….. thanks in advance…. Found some saying 40-125 par others 150 to 200par….

Hi, planning out my build for the new house. 235g display, 300g stock tank sump with a standard 75g and a 42"x42" frag tank sharing it. Sps dominant with a few encrusting lps (leptos, cyphastrea, etc.). Using the LEDs from my previous tank in a new hybrid fixture (61" Aquaticlife Hybrid...

Looking to see if anyone has one for sale or knows of a site that isn’t out of stock. I can’t seem to find one anywhere. Thanks in advance!

Hi all, I'm getting my first Bubble coral tomorrow and am trying to decide placement. I have a couple options, both with relatively low flow. And now it's come down to light level. What PAR level should I aim for with a Bubble Coral INDO? Thanks!

Bulk Reef Supply essentially does the PAR meter rental where you can return the meter within 60 days for their $100 restocking fee. But I was also reading the reviews and most people said it was useless without the handle, which is $70 to own and can't be returned like the meter I don't think...

Is 150 PAR enough for a derasa clam? The spot that I’m looking at is around that PAR level with an AI prime.

Hi all, I will give some more details to the title. I recently started my adventure for the first time with saltwater aquaristic, so I have no N years of experience for supporting my claims. I come from freshwater, and before that terraristic (bearded dragons, newts, frogs etc) and a common...

Wanting to switch my light program to the BRS recommended for LPS dominant tank. Not happy with my current program as it has too much white, and far too many data points to adjust the white. In addition to the white light I'm needing to increase the PAR after testing, as I found the bottom was...

Hello all, I am setting up a 3ft wide by 1 ft deep by 2 feet tall reef tank and I am planning on lighting it with AI Prime 16HDs. I have 3 at the moment and I am trying to get a read on how 3 primes can be used to achieve a mixed reef with such a deep tank? Any help and experience is...

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...

Currently I have 2 of these 32W Nicrew marine led lights on a 125. Trying to encourage the growth of coralline that came on one of my snails. If anyone could tell me a good setting for blue and white lights I would appreciate it. Currently have it set to 40 Blue 50 White. But had it set to 85...

Hello there SoCal Reefers! (: I’m getting new lights in and I wanted to rent a PAR meter from a fellow reefer in SoCal for a day. Let me know if anyone has one available. Thanks! #happyreefing

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...

Some of my corals have been struggling and I finally decided to get one of the Apogee 510 PAR meters from BRS and see if lighting might be my issue. I have two Kessil A360X's on a fairly small tank so I've always assumed that I probably had plenty of PAR. Turns out, I had way too much, and...

Hello all, I finally got around to renting a BRS par meter. I have several SPS in my tank and I wanted to be double sure about the amount of light I was giving my corals. I'm currently running 4 Kessil 360x and 2 80W T5's over a 72" 220. At the peak of the lighting schedule, the Kessils are...

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...
