105G T5 Lighting - Bulbs?

My first post on Planted Tank. Long time Saltwater hobbyist - first time freshwater.

I've decided to learn more about the freshwater hobby & design a 105G (48"x24"x21") freshwater planted tank.

So, I'm learning day by day in regards to many differences. I plan to retro fit 4 (maybe 6) 54w T5 LET Lighting bulbs to a canopy.

My initial thought was:

Front
Aquablue Plus
Aqua Pink

GE 6500k
Aqua Flora

Then I start to wonder, how do saltwater popular bulbs such as ATI Blue + & Actinics fair in freshwater? Any benefit? Any experience?

Curious to what a couple 'freshwater planted guru's' might think about the 4 bulb combo listed above & any notes/advice.

You don't need actinic <420nm light at all. But you do need blue light through red light for various reasons. So before you jump in to the deep end of the pool with such a large tank read up on lighting requirements of freshwater aquatic plants, which btw, isn't different than terrestrial plant requirements with one exception. Submerged plants do well with lower light levels.

This thread may be helpful. They also have 150 gallon tank and used led lighting.

Thank you, Steve. Believe I'll stick with a 4 bulb T5 retro fit. I'm more curious about my bulb combo... I haven't much experience in the freshwater hobby & I'm interested if this combo will be aesthetically appealing & favorable to a planted tank.

I can always learn thru trial & error, but I think this forum could offer some great advice from fellow hobbyists.

Anyone care to comment on the bulb combo in my OP?

6700k or higher is generally what is used. Either 10,000k's, 6700k's, or some combo of the two seem to be the most popular. I personally run a mix of both and see great growth and color.

I have a open top tank so I prefer pendant type bulbs over tubes because I like the uncluttered look and easy access such a setup provides. .
I also prefer cfl bulbs that have a temperature of 5500K and high CRI >90.

BTW, My tank runs primarily off natural light all year and direct sunlight during portions of the year. So the light I use is mostly just to supplement on very overcast days.

There are high wattage cfl types that would easily light this size tank.

You also have fluorescent induction lighting.

And lastly you have plasma lighting. It's probably overkill but I've included it to be comprehensive in options.


I assume you are familiar with the drawbacks of each lighting option so I don't need to explain what they are.

Thank you again, Steve. I think my OP & question is being misunderstood. I'm not looking for lighting ideas... I'm more interested in 4 T5 bulb combos & is my combo a good one?

I'll continue to read & can always learn thru trial & error. I thought someone might chime in with T5 experience. I think I'm expecting Reef Central service from Planted Tank... I'm learning about Planted Tank.

Like I said, I light my high tech 55 with a bulb each of 6700k and 10000k t5HO
Your combo may wash out the colors a bit, but what looks best is entirely up to interpretation

If you can find a T5 in a 5500k in place of one of those bulbs that would be better than two light sources outputting more blue than you need. Remember plants need red wavelengths of light just like corals need various wavelenghts.

I Like the ati aquablue and purple plus
uvl red sun /455nm is not a bad bulb either but is very red, it needs to be used with other bulbs

for a 4 bulb fixture
i'd run 2 6500k's an ati purple plus and a zoomed roseate bulb, or a geisemann aquaflora
