2 XR15 over 90 gallon

For the life of me can not get any sps to grow in my tank, I am trying to see what some other people use for their lighting schedules with xr15s.

Look up the AB+ schedule... that’s what most people use for SPS

Measure PAR 2 XR15s may not be adequate for a 90g with SPS.

I had an x15 over a 56 gallon tank. Par was to low to grow sps. I know everyone loves them but you need to add a bunch to make them work. I solld mine and replaced it with a Kessil like my other tank.

Thanks everyone

Look into a t5 hybrid. I bet things will turn around for you in no time assuming lighting is the issue.

I run them on a 4 ft 150 and I grow sps. But I also supplement with 4 T5 in an aquatic life fixture. Blue plus T5 and AB+ Acros in the top half and monties and birds nest every where else. I do want to add two more though just to make it more even.
