What are the dimensions of your light? You tank is 24"x18"x18". I think your light must be wider/deeper than your tank. Right? If that is the case, some of your 8 tubes may not even contribute much to your corals. How high above the surface of the water do you hang your light?
Anyway, Bucfan from the previous post has very good sound advice. Just watch your corals as you increase the photo period.
Good luck.
Go slow. 4 tubes 7-9 hours and 8 tubes 2-4 hours. There are many who run 8 tubes 6 hours or more but you got to watch your corals and feed a lot. I would say start 8 tubes 1.5 hours and ramp up 15 mins every 5 days to 3 hours. And start with 8 tubes 5 hours and ramp up 30 mins each week till you get to 8 hours. Your corals will tell you if they getting too much light. In this hobby patience is key. We've all been burnt trying to do things quick.

I am curious if anyone here can compare how this fixture grows and colors SPS vs the straight T5 fixture? Maybe someone who has run both on their system? Thanks.
12-15" above water level. I have a 27" deep tank and lamp is 14" above water level. 30-50% for LED, but start low. I have mine at 50% max after 8 months. T5 6-10 hours for 4 bulbs and 2-3 hours for 8 bulbs depends on your coral.

Hey all!
I just recently joined the ATI Power Module Hybrid club! My tank is 36x17x17, and the lights are hanging about 12-14 inches above the water line.
It's a 36" fixture, 4 bulb:
Blue+
Blue+
Coral+
Blue+
And I currently have the LEDs set at 30% intensity, while running my T5s for 8 hours.
How strong are these LEDs? I was previously using 2x Radion XR30 Pros over this 49 gallon tank at 40% intensity.
My tank is SPS dominate. Any help on intensity would be fantastic. Thank you

Welcome! You should be ok starting low with LED 30-35% is good with ramps on either end. I'd turn the T5 down to 6 hours and work back up to 8-9 hours. You have a 4 bulb lamp so PAR is less than 8 bulbs and more forgiving. I prefer using this lamp with T5 as prim light source and LED as only supplement.

I have a new 8x54w LED Powermodule on its way. Anyone have lessons learned or important tips? I plan on starting out slow and raising the fixture relatively high to avoid stressing out the corals.
Right now I run five T5 tube (it was seven bulbs but a ballast died on me) and two XHO reefbrite strips. I know the PM will have way more light.

2X 36" units would work. You'd have 6 inches on the side of each unit since you split the difference between the length of your tank and the 2 units. There may a bit of LED shading to the sides but you could place your low light corals there. If money not an issue go with the 48".
That looks pretty low to me. This is my schedule which I've ran for a year now but it's barely changed in that time. I went from 2 x Hydra 52 to this, and never saw any issues with my corals from too much light
