Should i increase the intensity?

[The_Barrs_Reef]

So I have upgraded from a 30 gal to a 120 gal.
I went from 1 ai prime hd to 4 ai prime hds running saxby and my corals loved it.
my question is my new tank is about 2 times as deep as my old tank. Should I increase the intensity of the lights now or will it be fine.
Thanks in advance!

If the distance thru the water from the surface to the corals has doubled, yes, turn up your lights. Light travels through air pretty easily, but water really slows it down and reduces the PAR quickly.

Be careful if you don't have a PAR meter.

I'd suggest a couple of 10% increases spread out over 2 weeks. But it depends a lot on what levels you were at with the old tank.

Go slow. There are PAR maps with primes out there, so at least find some and guess before you go too high - see what Google can find you. Slow will not hurt anything, but going too fast might.

These are not super powerful lights, so you can rest a little easy that they will not fry stuff like others can.

I just googled "ai prime par map" and found some videos and posts that should give you a good swag sans a PAR meter in your home.
