Thank you, that aquatic life 24” fixture is the exact one that is on my tank. BRS did a video with that fixture and an ai prime that gives settings and par numbers. You should check it out.
I still have a whole list of light videos to watch from them Haha. What's your stocking like? Coral wise?

Mid tank and up is all sps frags, several zoas and palys, a nice big Duncan that started around 7 heads and now has well over a hundred some acans a scoly and a nice octo. Everything was bought as frags and grown. A lot is still frags, takes patience.

That's my favorite though is watching the frags grow into a colony. What's your lighting settings on your hydra? And schedual? All look like.

That some odd hours. You work nights? So I'm bad at math but that's only what 5 hours?

How long have e you been running those percentages? Do you do the ramping up and down through out the day to stimulate "clouds" ?

So then wouldn't 2 AI primes be better for that?

No, I said a pair of AI 26HD's, not one, two. Unless I typod really hard and that wasn't clear lol

If I wanted to use AI's I'd use two AI 52's. for me, and my needs.

For you T5 can be just fine. I was putting my own anecdotal experience in just to show how different needs can be.

Yeah I work odd hrs. My hydra starts ramping up at 9am to the 75% where it stays for 5hrs and then ramps down for two hrs. T-5 run for about 8hrs a day I just stagger them coming on and off so it’s a more gradual light change.

He uses an AI prime with it and still gets great numbers, but do I really need that high of a par that far down in my tank when they say most lps and softies prefer 50 to 75 par? With the AI prime and that hes getting about 150-120 all the way to the bottom on the same size tank as mine.
You don’t have to run your prime that high. I have lps and softies in the bottom of my tank and they’re fine, they will adjust to higher light just need to take it slow.

I may go that route then if I can use a AI prime. Cheaper and still same results. Get the blanket from T5s and spectrum from Ai
