Par meter vs sps's

[renato120]

Hey guys, I bought a par meter it will be here Monday. I dont know how to play with it.
For sps's what should it read? My corals are bleaching, and I want to make sure if Im getting enough lights or not enough lights.
Thank you.

Do you have LED's?

Fixture type, coral height.
Also no3 and po4
Typically if you dont have enough par/pur they will turn brown with proper nutrients
If they have too much par/pur with lack of nutrients they will bleach, or expel zooxanthellae

Oops missed a question! My sps are in the 200 range under led

No3 5ppm
Po4 0

Hmm *thinking*

I am guessing alkalinity around 8?

Yup par meter time! Growth tips are white, which shows good fast growth.

What the par meter should read for sps's?

Now we are getting closer!
At 5ppm no3 and 0 po4 alk might be pushing growth too fast
200 par

 

[renato120]

So 200 par should be the reading?
Right now the fixture is at 9inches above the water. 16 inches from the sps's and they are all bleaching. Im curious to know what will be my reading. @twilliard

More food
How old are the lamps?
Im not a t5 user anymore but when I was I changed them every 6 months (driven by icecaps)

I shoot for no less than 200

They are 7 months old.
Always running 100%
I feed the tank twice a day. With the food I feed oyster, acropower

Ya once the meter shows up lets check it out.
But I am not thinking its a par issue
