Light intensity?


Can someone please rate my light intensity! Today at the aquarium store the clerk gave it a uncertain rating of "I would think at least moderate low". At the same time I also picked up some rotala macranda thinking at the price it was worth the gamble. Will my light setup be enough to grow this or is there a simple upgrade I could make to improve my light intensity (such as bulbs)

Currently :
36g bowfront
T-5 fixture with (2) 6,500 bulbs

Kinda depends a lot on the fixture. Should be more than plenty though either way.

looking at the plants in the bottom left of the photo i would say you are low-med light which is fine, might not turn rotala red but it will grow

The picture looks pretty good lightwise, and is thankfully a good picture. I don't know what kind of lighting you have but if you have a tube that came with the canopy stock, you could buy one of the 6500K name brands at the lfs. I heard they're a little brighter. I'm very interested in LEDs, but I'm trying to get the cash together.

Your tank is probably about 20 inches high, and the light would be about 18-20 inches above the substrate, if you have 2 inches of substrate. If the light is a Coralife T5NO fixture you don't have enough light to grow anything but mosses, anubias, etc. If it is a Coralife T5HO you probably have good low light. If it is a better quality T5HO light you probably have medium light.

Would I get more light by replacing one 6,500k bulb with a 10,000k bulb or would this not be recommended?

That number refers to the color spectrum, nothing to do with intensity. The only reason to change is if you like the look better.

So what would my most economical solution be to increasing my light intensity? Just find a standard high watt desk lamp at staples?

Edit: would just adding my old 24" current satellite be a good solution?

Can you take a photo of the light fixture you now have, that shows the bulbs and reflectors? Without knowing more about that fixture it isn't possible to recommend what changes you should make. And, it is also difficult to know what to recommend without knowing what plants you want to grow, and how much work you are willing to do to grow them.

Here are my lights as of now, a standard Aqueon t5 fixture with (2) 18w 6,700k bulbs and I just added a 24" current satellite led which I dug out of the back of my closet (not sure if it adds much in terms of usable light) I run the lights 10 hours a day 5h on, 4h off, then 5h back on. I water change weekly 10g-13g, dose 3ml 2 times a week with seachem excel, root tabs sporadically for my swords and add 3ml daily of api co2 booster (till I can save start up money to go gas)

For plants i have:

Amazon sword
Mini sword
Vesuvius Sword
Potamogeton gayi
Broadleaf ludwigia
Rotala indica
Rotala macranda
Anubias petite
Anubias barteri
Flame sword? (Echinodorus spp)
Crypy Wednitt
Banana plant
Java fern

The T5 light is giving you just barely enough light to grow anything. The Current LED light I know nothing about, but with both lights I suspect you have enough light for the plants to do well.
