Par in 75 gallon

briane1978 · Nov 15, 2024

I'm running 2x Ai 16. 2xai 32 with a wwc program just back down on %
Blues do 30 min ramp up to 100% for 4 hours then whites and Blues on at 74% for 2 hours then Blues back to 100% 4 hours. Wwc was doing Blues at 125% and whites at 100%
Par on top half with just Blues at 100% range 600-800 all the rest of the numbers are under whites and Blues
Everything seems to be growing tank is getting about 6000ml in 24 hours with kalk holding alk around 8.3 -8.7 ca is on lower side at 330 for now
I have been out of the hobby for 8 years have never tested par till now
Meter is apogee 510

You could raise the lights if you want lower par on the sand bed. I don’t run whites at all.
I have 2 AIs 16hd on the left side and one 32 on the right. 75g tank. You probably could pull the 16s and leave the 32s IMO unless your going for acros and if that’s the case I’d raise the lights a bit…

I would had loved to went up on the lights but soon as I do all I will see is blue on my screen as for corals mostly sps is the plan as of now there is 31 different sps in the tank this was pretty much what wwc runs just dropped the % down

Get some 3D printed shades

All my lights are 12inchs above the water surface what about yours?

8" above the water some of the rock is only about 8" below I'm use to have a larg tank this tank is hard for me to figure out at the moment but everything is growing.
And I do have a 3d printer that will be here today I guess I could search see if any files for it

Definitely figure out how to print some! Or just have someone print them for you lol

It’s definitely helped the light spill and raising them up will lower par enough to help you keep things that like lower par - some blastos and various other corals don’t do well at all higher par.
