Should I add 48 in T5?

Hi all,

I currently have a medium-ish tech planted tank with Co2. I am running the Co2 at approximately 3 bps, and I have a Finnex Ray 2 for lighting. I also add a capful of Excel once per day, and osmocote root ferts once every couple of months about an inch into the substrate. I have a spare 48 inch T5. Should I put the T5 on the tank? Or is what I currently have enough? My concern is that some of the plants are slightly shading some of the lower plants closer to the substrate and I want all of my plants to get an adequate amount of light. However, I do not want to much light because I am worried about algae blooms. Let me know what you think. Thanks!

It sounds like your issue is with spread vs light intensity.

Adding a single T5 bulb will not make huge gains in PAR but it could be beneficial if you position it in a way so that it hits the plants being shaded. As long as your tank can handle the tank then go for it. I would turn it on for like part of the day to start and observe if you have any algae issues.

IMO if the plants are not showing signs of being deficient I would not screw with it. Also - if you are not dosing ferts in the water column you should get on that. They will help out with growth and eliminate nutrient deficiencies (if done right)

I'm adding flourish complete and flourish iron (capful about once per week). Also, I just got many of the plants so I have not monitored whether or not the light is enough for them. Should I wait to see how they do and then add the T5 if needed?
