PAR Question

[wisnia99]

Hi guys,
I have measured my par levels.
Im running 3 xr30s pros at 65% should I be bringing my intensity up? or the current par is enough?
My tank I mixed reef.

Thanks!

Are you seeing any reason why you should?


But if you're just wanting to, you can ramp it up a little to get 350 at the tops and put the acros up there.


Let your corals tell you if they require more light.

The corals are doing well but im starting to add acros and not sure if I should be higher up.

If you ramp your blues to 100% and and add 15% more white to spectrum slowly over the course of 2 months you’d have ridiculous growth on ur SPS and LPS .

I run a mixed reef with Red Sea 90W
100% blues
25% whites
6% moon
PAR 682 at the top
Half way down 400
Sand bed 150-200

Wow that is bright!

What par meter are you using

 

[williamCreery]

Sps and LPS can get up to 800 but acclimating them correctly and slowly.
800 tho will just wash their color out.
My secret number is 650 Par at the top. For all SPS and LPS. Colors are at the best at that par and growth is immaculate.

What par matter are you using

MQ-510

Again what par meter are you using to see those numbers. Edit sorry didn't see your answer

 

[Cichlid Dad]

Must be some super coral

 

[williamCreery]

first corals getting hit are

•Disney
•golden jawdropper
•purple acro (I forgot the name of)
•Blue dreams
• many more

Half way down rock work
•Stylophora pink, purple, green and blue.
•toadstool.. etc
•zoas

Sand bed
•clam
•more Zoas
•rainbow acans etc 3 other kinds
•ultra gold mushrooms.
•ultra rainbow Yuma
•rock flowers etc..

Based on our own experiences and the information World Wide Corals has shared with all of us, an SPS Acropora dominant tank should be getting 200 - 300 PAR throughout as much of the tank as possible.
There will be peaks and valleys directly under the light and in the corners based on the simple nature of LED light output but a PAR meter is going to help you find the sweet spot for your particular lighting choice and tank size.



PAR values in WWC display tank



A handy trick is print out a photo of your tank, then record the measured PAR numbers in various spots throughout the tank. Then adjust your light placement and intensity to find the most even coverage within the desired PAR range.



Coral placement can be something you address and experiment with after documenting the actual PAR values in various areas of your tank.



In LPS or lower light demanding tanks the target is 50-150 PAR throughout the tank and often the lower the better.
PAR is absolutely not horse power with most LPS corals and getting the PAR that low with LED’s can actually be a challenge, especially if you rely on your own eyes. Many popular LED lights need to be dialed down by 25% - 30% to land in this <150 PAR range for lower light demanding corals.


I think imho you would be fine with the par numbers you have in your tank.

I mean I take the risks but slowly over months of acclimating not just a couple months, about 8 months. it’s possible to be at super high Par for super fast growth and unbelievable coloration.
Here’s my schedule

If you look at his tank it's a mixed reef, heavy on lps, zoa and mushrooms. I only run mine @ 200 par on top with mostly old school acro at that level. Most of the rest of the tank 60- 165 par. Not crazy growth. But I don't like the pastel colors. My hammer and frogs grow like crazy though. Zoa's multiplying well . I use 1 xr15, and two viparspectra 165 with the lenses removed on a 75 gallon

RS90's are not XR30's The RS spectrum is completely different than a Ecotech. I have run both brands and each has its own use. Par is not PUR.
Just saying....
