Kessil a150w on a 5 gal

[Bryan_k47]

Any of you nano lovers running the ocean blue a150 on a tank as small as 5 gallons?
Your thoughts ?

Thanks

Planning to bleach the corals instant?

I've read about people running the sane set up on forums in the states with success
Aquarium illusions in Edmonton has a Deep Ocean blue on a 10 gal and it looks amazing

I should add its a zoa/paly only tank

Seahorse are assuming it will be too intense or know from experience ?
I have a par 38 halo on it now

It is too much light for the tank, especially since it can't be dimmed. The Kessil's put out a very strong beam of light, especially directly beneath them. I took PAR readings on my A350, while it is a more powerful light (90 W vs. 30 W), it uses the same technology and I believe it gives you an idea as to how much light Kessil's emit.

I have a 150 on my 18x18x18 cube and it's a lot of light. I think it's way to much for a 5g.

Think it would be okay 12-14 inches above water ?

It might but you would get a massive ring of light around the tank. Look at it this way, I have seen guys running 6 food tanks with 4 sometimes only 3, 150's. It's a beefy little light. If you already have one, worst thing that can happen is you try it and see if you like it and if it works out. If you don't and are going to buy one, save your money and get something smaller.

Yeah I have one. I was gonna use it instead of a par 38. Just looks tidier.
The 5 gal is actually in my bathroom lol. "The Office Tank"
I'm gonna give it a shot I guess. I will start as high as I can with it and creep it down

I don't use Kessils but I have a friend who uses two over a 4' reef. I do use similar focused pendant lights (but DIY) and they are only 50w total over a 2' cube 60g. They market the A150w as being the equivalent of a 150w metal halide even though it only draws 32w of power. I don't think most reefers would ever consider lighting up a 5g tank with a 150w metal halide. Something in the 10-12w range for LEDs would be plenty for a 5g and even that is way more than what I use. I have 280w over 165g (1.7w/gallon), 50w over 60g (0.83w/gallon) and 60w over 34g (1.76w/gallon) mixed reefs. These are all dimmable and I had them all dimmed down for a couple of months when I first installed the LEDs over my tanks and I still got bleaching.

You're planning to blast 6.4w/gallon using an undimmable light on your little 5g. I would put money on bleaching your corals and making your tank uncomfortably bright for your fish. BTW, zoas and palys that are blasted with light tend to grow smaller in head size compared to polyps grown under normal or lower light levels. If you see this happening, that's to be expected.

Most reefers I know have had to start off at 50% or less and a lot of them still experienced corals bleaching before they adapted to the more intense LED lighting.

The PAR 38 should be perfect for a 5g. All my tanks and most of my house lights are LED so these comments are based on experience with LEDs over reef tanks, not just pulling assumptions out my "bleep" ;P

It should be fine. Aquarium illusions has one over a nano, no ill effects. Keep it high.
