Too much light for planted aquarium?

[Gladmist]

I recently bought a new light hood for my 29 gallon 36" long x 16" high freshwater aquarium. Didn't realize at the time it was for T5 bulbs and didn't know the difference. Now that I do, and I am trying to grow freshwater plants in there I am wondering if this will be too much light for the size of the aquarium. I have 1 39 watt 10,000k and 1 39 watt 6700k in there. I do not want to use a co2 system. Is this too much? If so is there a way to tone it down? Any help would be much appreciated. Fish in the tank are happy and healthy and consist of 2 Bosemani Rainbows, 2 turquoise rainbows, 1 Glotetra, 3 cherry barbs, 1 panda Cory, 1 Julii Cory, 1 otocat and a bn pleco

It is definitely too much if you don't want to inject CO2 and have a very regimented fertilizer addition program. You could run just 1 of the two bulbs (either would be fine) and that would make the tank much more manageable without CO2. Even then, it will be a very good amount of light for almost all plants that will grow well without CO2 injection.

Not sure if those lights are too much. Those should be okay but I heard 6700k light bulbs are best for plants since they mimic sunlight.

Recently I bought a 29 gallon also and just got done cycling. My lighting is...well I would say alot. I have a quad t5 lights, each 6700k, 24 watts each bulb. My plants are growing great, especially my water sprite! Just recently bought an anubas nana and it already grew a new leaf

I am also dosing Flourish Excel with it, giving it a carbon source and preventing algae growth. But I have lots of brown algae right now (heard that is not really algae but called diatoms; heard its also normal in a newly set-up tank)..About to get some fish to eat those!

Sorry misread your 6700k bulb for 6500k. Your bulb is fine
