Just getting back into the hobby after 10 years away. Last time I had all MH (400w) on a SPS dominant tank. This time I’m going LED. New tank is a Red Sea 425xl - so dims are roughly 47 x 22 x 22 - and I want to do all SPS again. I’m new to LEDs and after reading a lot I’m still not sure if I should go with 2 Hydra 26’s (or maybe 3?) or just 2 Hydra 52’s?

I have a 450 and 3 26's I would prefer 4 for more even lighting. They cover 18 inches well, rated for 24. They get dim fast outside that 18 inches. Being that that tank
in deluxe model comes with 2 I would say full SPS you would want 3. Look at the AI website signature series tanks. The one has 3-52's on a reefer 250 the other has 2-26's
on a 30 gallon. I cant speak for the 52 I have no experience with them.

Yup just found the tank - I already picked up 2 52’s - think I will start there and if a third is needed I will put one on. Can’t believe he has 3 on a 250 - though I am brand new to LED lighting so that could make sense. Do most people run the lights at the same height off the tank for better coverage?

LEDs have very directional light. Corals can have plenty of light on one side and virtually none on the other.

There are a couple of ways to handle this.

You can do a hybrid setup with LED and T5.

Or you can run more LED lights and hang them a bit higher and let light overlap smooth out the lighting.
