150 Gallon Lighting.

Hi!

I recently purchased an AquaticLife T5 HO 4-Lamp 48" fixture for my 150 gallon (48"x24"x31") Manueli's tank. As most of you know, piranhas hate bright light so I'm just stumped on what bulb combination (4 bulbs) to use for healthy plant growth while not having the tank too bright. I was just wondering what bulbs you guys would recommend for optimal plant growth. I do have fluorite for the substrate but I do not run a CO2 system. I will get some pictures of my tank when I get home from work.

I mean, they don't have to be kept in the dark or anything haha. This is just the first time I have had a quad fixture and I just overthink things sometimes. Is there a specific manufacture you guys recommend for the bulbs?

Thank you everyone for the info! I just finished setting up the light and will get a picture as soon as I get a moment.

I decided to go with Giesemann X2 flora and X2 midday. The fixture has a built in timer for blue white and night. I'll just tinker with it until I get everything nailed down.

my current plant stock is just jungle Val and two amazon swords. I have the jungle Val on the far right side next to the power head so when it takes off, it will give a nice thick cover over the tank. Is there a good lily you guys would recommend or any other plant that may help with coverage?

I have had the Manny for about 7 months. I feed him a diet of krill, silversides and Repashy aquatic meatpie. While not as shy as some piranhas I have been around, he will eat in front of you if you don't move haha. I will be throwing on a black background tomorrow to help with covering any extra light entering them room and give him a more secure feeling.

Thanks again, everyone!

The background is going on today. I will post updated pictures when I get the chance.
