Hey guys, is this enough par or should I add a second light?

I'm thinking about growing some GSP.

GSP don't need a lot of PAR to grow.

Light looks bright enough but best way to determine is with a PAR meter rather than appearance to the eye but dont see an issue with light deficiency

ummm I think maybe some missed it lol.
a500x with the narrow reflector on a 10g should be fine for gsp .

Whoa, whoa, whoa. It's a 20 gallon, sir. Let's not be ridiculous.

In all seriousness, the prime that I had on before was leaving the ends a little too dark (24" tank), and I had the kessil laying around, so I figured why not? Lol. I knew it would be a lot, but I was still shocked to see 3500 PAR at the top of the arch.

Atleast the light should last a long time running on like 4% power.

Are you saying you have 3500 par. That doesn't sound right.

That's what the meter says. It's a very powerful light made for 4ft tall tanks on top of a 13" one.

I would check with another meter. You would cook any coral with that much par. Usually par is in Hundreds not Thousands. Maybe that number needs a conversion I'm not sure.

naw its probably right. That light is a laser cannon. Probably take off the narrow beam reflector get a lot of light spill but cut the par in to a third.

Or mount it to the ceiling.

Or in the next room and bounce the light off of a mirror
