par rating for corals

[White Hair]

just bought a Fluval 3.0 32 watt with par values at 3”-376, 6”-222, 12”-90 18” 47, question is can i grow corals with this light , if so, what type, and would it be good enough for them to grow and be healthy, next question is if i add another of the same kind does it double the par value, the price for another same kind is $150, if not should i try to sell this one and buy another, what brand and strength. Figuring i could sell this one at 50% that would give me $75 towards another, my tank is 30 gal 18” deep, thanks

Two will double the PAR, well, sort of. The areas will be separated some so the coverage will increase and the PAR wont quite double. Looks like the PAR levels you're getting are acceptable for just about anything you'd want to grow; corals that demand higher lighting levels will need to be placed toward the top with lower light demanding corals will be placed at the bottom. When you place a coral, be mindful of it's shape when it grows out so that you dont inadveratantly shade corals below. Keep thin branching types up top and plating ones toward the bottom (provided there is enough light down there for them). I'm not familiar with that array's spectrum though.

Edit: What did you use to measure PAR?

It was listed on the side of the box

I gues i should have asked first, if anyone was using one of these lights and if so, what kind of corals they have and what kind of luck they are having

Someone did a self review here on the Fluval Marine 3.0.

Fluval Marine reef 3.0 review

For all those curious I’m doing a review of the Fluval Marine reef 3.0 for a low tech light it’s pretty good, the app is decent although without a par meter you might find yourself lost adjusting the spectrums the light by itself will support softies however for any LPS and SPS corals I would...
