Hi everyone, I’d like to share my personal experience about magnifica anemone and lighting.

A year ago I did a post about that giant magnifica that I bought, which had a bacterial infection and was bleached. Due to laws in Canada I couldn’t get my hand on Cipro (usually used to treat sick Mags) so I tried with Azithromycin which, worked well. Here’s the link to that post : https://www.reef2reef.com/threads/m...ment-with-azithromycin.1061976/#post-13597293

Since the treatment I did a zooxanthellae transplant (thanks to the bubble tips from my other tank for those tentacules sacrifice) which helped the nem color up in a few weeks.

Here we have a pic of that nem 10 months after treatment, lost a bit of size (when it was bleached) and coloring up.

A month after that picture (while I was away per usual) one of my Kessil a360we decided that it’s time had come so 1/2 the tank got the night treatment for 2 days (luckily it still had some spillage over it) so I saw a 48 inch cheap T5 fixture on marketplace and decided to buy it for a temporary replacement (in the worst case) and if I liked it well I would keep it. So we’re now 1 month in and ….

I’ve never seen that anemone stunning like that, the tentacles have grown longer, thicker, it’s stretching more, not reaching to the top of the tank.

For reference, it was blast by a Kessil a360we + a white beam and would seem to move a lot looking for something. Now with the T5 it went for the high flow area since the T5s offer an even light spread. (Bulbs have been changed since I bought it)

Maybe the T5 heat also provides a more sun like feel to the anemone and helps it reduce stress… hard to say it won’t tell me.

So in my case, T5 were the missing ingredient to full success in my opinion, so I decided to share that experiment with you all and hope that it may help! I’m curious to hear other Mags owner on their opinion about light, maybe mixing LED and T5 you get the best of both worlds.

Let me know!

thank you for sharing this, extremely valuable practical observations. I am a self-proclaimed Kessil Fanboy, and I admit it is such a shame that even with all the advances in LED technology, T5's just can't be beat!!!

Honestly I was the same way, I was very doubtful to get T5, I did for emergency but honestly I am now converted. Is it different than LED? Yes. But the results on all my corals and especially that Mag shows why it’s still around!

Here are the bulb choice :

6 54w bulb front to back all ATI bulb :

Blue+
Actinic
Aquablue special
Purple +
Blue+
Blue +

Tried :

Blue+
Blue+
Actinic
Purple +
Blue+
Blue+

But the nem didn’t seemed to like it as much and neither did I (too blue)

I might test with a 14 000k instead of the Aquablue special as well in the future

I think any light is OK as long as it has reasonable full spectrum and adequate brightness. It is hard if not impossible for us to over light a Magnifica. Years ago, I had mine right under a 400 W MH bulb 10 inches above the water, and the anemone just a few inches under the water level. Right now, I have full spectrum LED and three flood light LED bulbs (from Home Depo outdoor 6000K flood light 26 W each (not Wat equivalent but actual wattage of the light)) shine right on my Magnifica at about 6 inches under the eater surface. My LED light are 160 W cheap chinese LED panels. Two of them right over the anemone at 100%. Light are about 12 inches above the water line.
My Magnifica is doing great for the last several years, as healthy and happy as any I see
