T5 retrofit questions

[Cthulukelele]

So I am running 2 MarsAqua 165w above a 120g tank, and I want to retrofit my canopy with t5s to supplement. I don't like all the shading (most corals seem to be doing fine I have a mix of SPS LPS and a few zoas)

A few questions!

What kit should I use?
2 48" or 4 48"?
I plan to use ATI bulbs. Which bulbs?
Should I mix and match?

If you want to cure shading probaly just two.
To boost par and let the t5 donthe heavy lifting 4.

Fwiw , each tube is about 150-180 par at 12in.
So four tubes would add 700 ish par to the top of the tank.

Mix and match. No guess is wrong. Blue + or coral plus or a purple plus in ati.
You can rebalance the color with the led.

Thanks! Seems legit! I will probably go with the 2 bulbs then. The leds get super bright so I am not too worried about the T5s doing the heavy lifting.

I am thinking maybe a true actinic and a coral plus. These seem to have the most of the spectrums I lack on the Chinese black boxes, but maybe actinic and blue+. Hmmmm decisions decisions.

Any flavor combinations you really like?

Actually, the actinic might not be a good Choice as it’s the lowest par (and brightness ) unless the B.B. doesn’t s have the pop you want. It’s basically a black light. (Yea I’ll tske that back. )

So much is personal choice though. I run my SBreeflight at 1:1 ratio. Warm for most folks so I’d b+ c+ for that.

If you run a blue look maybe b+ b+. And balance with the led whites to taste.
That might be the safe bet. Especially if the tubes are close to the water, it’ll blend better.

Myself , on a full ati w b+x4 and p+x2 and TAx2 , (at my lfs display ) I wanna Ralph. Some like it though.
Lol.

B+ and C+ it is! I actually run my tank very warm, but that is mainly because of my current PAR options. If I want to grow sps with these lights, I have to jack up the whites more than I'd like to get the PAR there.

I think tuning down the led whites and adding a c+ and b+ will give me a nice faint blue glow with a little more pop and very little shadowing which I am looking for (based on the YouTube videos I've been neurotically watching all evening lol).

You have been incredibly helpful! I also agree about the super blue "the drugs are just starting to kick in" candyland coral colors floating in windex. Not for me

Hahahaha
Glad to help!

I have the LET retro kit from BRS and they use the same ballast at ATI fixtures

Do you know if they use the same reflectors?

IMO the reflectors in the kit bigger and more parabolic kinda reminds me of the old ICE CAP reflectors.

I wish I had a controller so I could use the dimmable retrofit! My coral don't love the first 5-10 minutes after the lights kick on lol

I don't think you will have enough room to go 4 bulbs and not shade over the LED fixtures on a 24" wide tank.
I run a 2 bulb retrofit on the outer ends of my 4 Radions on a 180g and I need to turn the reflectors inward so that the front and rear glass panels are not blasted with light. I ended up using ATI AB Special and while it took a little time to get use to the 12k output, I like it. I only run the T5s for 4 hours a day during the peak of the LEDs.
