Here's my tank:



It's 6.6 gallons (but probably closer to 6, because I have to leave an inch or so at the top for my betta), and about 9" tall. Right now it has a T8, "15w Red" bulb in it, which is what it came with. That is what it says on the bulb, so I'm not sure how many K it has. I added some dwarf hg and baby tears yesterday which I believe are moderate light plants, so I do believe I need to upgrade the lighting, however I'm having trouble figuring out what I need. The general "rule of thumb" is 2-3 watts per gallon, correct? Or is it more for moderate light needs? Also, is 6500K about right? Any help is appreciated, thanks... big noob here.

Your Lighting Question

Good morning Penny...

What you want is a 6500 K bulb. It comes the closest to natural daylight at 5500 K. A T8 will provide good distribution.

I still use the watts per gallon rule. It's simple and provides a good starting point for deciding on the proper lighting for your tank.

If you have approx. 2 watts of light per gallon of tank volume, that's enough for the majority of the aquatic plants on the market.

Lighting is most important, but a close second is fertilizer. I like to use hydroponics liquids, but there are others.

Last, you have a very small tank, so it would be best to either keep very small fish or keep very few.

Yep, I only have one betta in there and don't plan on adding anything else. It's HIS tank ;)
Though someday, when I have the money, I would love a big angelfish tank!

So 15 watts is about right then? I just need something with more K, which is what I figured. (I think the red lights are around 4000K?)

Thank you!

Oh and I do use some liquid fertilizer, but definitely plan on picking up (or ordering) some root tabs here soon.
