Lighting help

[Nickyfish]

Hello friend I am new to this form I have a 72 gallon bowfront aquarium that will be used mainly for fish maybe some anatomies I upgraded from a 50 gallon acrylic. on my 50 gallon acrylic I have a 36 inch core life strip with two T5 bulbs obviously the new tank is 48 inches and deeper So I need more lighting I am very happy with the cor life fixture I have now so I was thinking of ordering the 48 inch dual coral life T5 fixture but I see now there is a LED fixture available on Amazon for about the same price I will list the specs below do you guys think I should purchase the LED fixture or should I purchase the Cora life twin T5 fixture which will be used in correlation with the 36 inch Coral life dual T5 I have now below are the specs of the LED light and coral life

The latest DA LED Pent series by Beamworks provides a high quality, energy efficient light fixture that replaces the typical single or dual tube fluorescent lights. Use the 10000K white and Actinic 460nm LEDs during the day and only the Actinic Blue 460nm LED during the night. The DA LEDs is fitted in a sleek and razor-thin fixture that will make any other aquarium light look boring. Long lasting LEDs with no bulb replacement required. Fixture is pre-wired for use with the optional timer module to program on and off times.

Or
The coral life just says 2 t5 bulbs I am assuming one is white and one is blue
Thank you in advance for any opinions and advice

Assuming you stick to just fish, either one should be fine.

Anemones are like coral. They have zooxanthellae (algae) that live inside them and do photosynthesis which helps to feed the anemone or coral. I can say for sure, but a 2 bulb t5 over a 20" or 24" deep tank may not be enough light for many anemones. It could work, but it's probably iffy at best. A 4 bulb fixture would be better.

If the led fixture is the one I found:
https://www.amazon.com/dp/B016P96UA8/ref=twister_B01KYELCSK?_encoding=UTF8&psc=1

It has 104ea 6500K, 16ea Actinic. That is a fish only led. Is that the one you are looking at?

For anemones to do well under leds they need at least a 50:50 ratio of white and blue as the zooxanthellae use the blue to do most of the photosynthesis. Most good and yet inexpensive led fixtures have a 50:50 split. They will add in a couple of reds and greens, maybe some violets (they may call them UV, but they are really just violet). There are several brands of led fixtures that make 32" or 48" versions that would be way more than enough for anemones. Look at Mars Aqua, Viparspectra, Euphotica and others.
