    Very Surprised by My Low Par (Kessil AP700’s)

    Hello all, Been reefing for 7 years now. The first 5 went really good had a 72 bow front with 4 ATI bulbs and grew corals well and easily. Monti caps, birds nest, stylo, and hydnophora were my higher light corals and then I had things like torches, zoas, war coral, green star polyps which all...

    Radion XR15 G5 Pro settings/par ?

    Hi, first post here. I have two Radion XR15 pros in my 36L x 24W x 20H with 4-5 inches of sand below. My lights are mounted on the Radion arms that I bought for the leds about 7 or 8 inches off the water. I am looking to house a haddoni carpet anemone in this tank as my "center piece" if...

    Easy High Light Corals

    Noticing the top 1/3 of my tank kinda bare and could use some suggestions on easy corals that I can put high that aren't just zoas or some invasive type coral. Got a leather and toadstool already higher up. Any recommendations?

    I need to add more lights... help needed.

    Hi all, My tank is 2 years old - I feel like I'm now moving out of the "novice" phase and am looking to push harder into LPS and then SPS. (As you can see I can grow softies like crazy lol!) Lighting is what I'm focusing on now. I'm looking to get my PAR levels up to ~200 mid-tank; ~100 at...

    Real life Radion G5 Blue PAR results w/diffuser

    So I thought I'd share my PAR measurements of my Radion G5 XR30 Blue. They are very different from the BRS testing, my 3" depth testing looks more like BRS's 6" depth testing. Not as PAR intense impressive as BRS tested. Once you drop below 4-5" the PAR drops substantially, however it holds...

    Just did PAR meter tests and found that lights are set way too low

    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...

    Kessil A360X Tuna Blue Lighting ☀️

    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...

    Which Apogee Instruments PAR Meter?

    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...

    PAR Readings

    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...

    So lets talk LFS lights and their frag tanks...

    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...

    Apogee SQ-420 vs SQ-520 for LED's

    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...
