par

Finally got to borrow a par meter to check some numbers. Turns out, everything is getting 1/2 to 2/3 as much par as it needs. This would explain slow growth and a number of issues with poor coloration and STN from base of some SPS. Should I increase 5% (smallest possible increment with...

Just got my hands on a PAR meter and I’m wondering what people in here keep their par at towards the top middle and bottom of their tanks. Never used one before looking for any advice

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...

For a limited time (sale ends Monday) we are offering 8% off on all PAR meters including the new PQ-510 with full-spectrum Quantum sensor, 2 meter cable and microCache Bluetooth micro-logger. The extended 2 meter cable of the SS2 model allows the microCache to be positioned further from the...

Hey all, I currently run 2 hydra 26’s (with diffusers) using the BRS modified AB+ spectrum (about 54 watts of power) on a 4 bulb aquatic life T5 hybrid fixture with 2 ATI blue plus bulbs and 2 actinic bulbs mounted about 10 inches high on my 4ft 120 gallon sps dominated tank. I am about to get...

I currently have a Seneye that I use solely for measuring PAR, but I am looking to purchase an Apogee Instruments meter to replace the Seneye because I no longer want to connect a meter to my computer. So, I am trying to decide between the MQ-210 and the MQ-510. I use only T5s, so I don't need...

I rented a par meter from BRS, here our my results. Is this appropriate par for a mixed reef? I have two red sea 90 LEDs running at 60% Blue and 66% White. I wanted softies and LPS towards the bottom and easy SPS at the top. I know the bottoms a bit high for low light coral and the top is...

Hello everyone! I work for a public aquarium and we are near the completion on a tropical butterfly house. Seeing as we will have tropical plants and being aquarium with coral systems, I was wondering if anyone had any recommendations for a par reader that will work out and in water? Does the...

Found on reddit. I would hate to be his neighbor!

Hi all, I purchased a 2nd hand Orphek Atlantic v2.1 b fixture, I am experimenting a bit with the intensity of the 4 channels. When I Google for information on what other people are running at, I have found little information, so trying to get a thread going here specifically for this light. I...

I have a few LFS in my area where I buy coral, mostly monti's, millepora, acropora etc. All in general look pretty good as far as color, growth, encrusting and polyp extension. Some shops have had the same corals for months too and they always look good. I am recently trying to dial in...

Hi all, So I'm really wanting to get a PAR meter and was looking at the apogee usb ones, but I run only LED's so I was wondering if the extra $100+ for the SQ-520 is worth it over the SQ-420. I have seen reviews where they say the margin of error isn't that much different or there is a...

So I’m getting back into the hobby after a 12 year break. In the past I did all 400w MH so LED’s are new to me. I currently have 2 Hydra 52’s over a 425xl in trying to understand the light output better I rented a PAR meter (MQ 500) from my LFS and I was kinda surprised at the readings so I’m...

I had my reef club's par meter (Apogee MQ500) last week and captured PAR numbers for the Mars Aqua 165w hanging over my frag tank. All measurements taken at 5" below water line.

Mixed reef Waterbox 230 just taken initial PAR readings. 5 hours peak lighting readings, looking for comments or suggestions.

What Is The Right PAR For Vibrant Coral Coloration and Growth? NEW VIDEO! Reef Aquarium Lighting Guide

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...

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...

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...

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...

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...

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...

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...
