My simple 47g FW tank - Page 2 - Aquarium Advice

Why 18000K? I'll be interested to see what your plants do under that lighting.

Because I have no idea what that number rating means, and when I was shopping, the higher that number was, the higher the price was.
I figured that meant that the number had something to do with quality or brightness. I was told that I needed more intense light to raise plants, so I went with the highest number. Can you tell I'm a bit of an impulse shopper?

What does that number mean anyway? Can anyone tell me the benefits of using a higher or lower number in different environments?

I don't know much about lighting or planted tanks, but I do know that research is key. Probably wouldn't have been a bad idea to know before buying, but it makes for a cool forum story

For info on plant requirements, make a post in the Planted Forum. We have many plant guru's that can help you out.

Here's the quick and dirty summary. That K (Kelvin) number represents the color of the light. Some light is yellowish, some is whitish, some is blueish, etc. I imagine that 18000K has a very crisp white with a nice blue tint to it. Higher K numbers are good for SW reef tanks, but I don't know they'd be good on a planted tank. While corals and SW stuff probably would enjoy that color of light (when I say color it's literally the area of the color spectrum the light bulb produces), plants prefer a slightly warmer light, between 5000K and 10000K. Now, that being said, I've never attempted to grow plants higher than 10000K, so I can't speak to what will really happen from personal experience.

Very nice looking tank. I was looking at your tanks in your sig and a sw tank sure would look nice there. LOL

I wish... I have a hard enough time getting the funding I need for this FW tank. I can only imagine how much it would cost to run a SW tank. I see some of the threads on this site talking about people using "extra" 150g tanks in the basement as filtration systems and all sorts of stuff like that. I think I'll stick with this for now.

I do have an extra 20g that I have been thinking about turning into an underwater garden though. Maybe in the next few weeks I'll look into that idea some more.

Here are a few new pics of my 47g tank. My Labs sat still long enough for a couple of good ones, and I even got one of a neon. The Moneywort and Cabomba just keep growing taller and taller. I used my 10g as a nursery for the plants until they had roots, so I could plant them without the Sevrum uprooting them.

SpeedEuphoria · 07-14-2008, 11:13 PM

Hey nice pics!
What fish do you have in there and how many? I know you have yellow labs, just not sure exactly what those are or much about them.

I may be setting up a simple 45G tank here shortly so looking for ideas

CatatonicBug · 07-15-2008, 12:32 AM

At this point, my livestock in this tank is as follows:
1 Turquoise Sevrum (the big guy)
3 Otos
2 Yellow Labs
8 Neon tetras
2 Red Minor tetras
2 Long-finned red minor tetras
1 Honey Sunset Gourami

I have had a few people discourage me from having the yellow labs in this community tank. So far, they have been fine, but I am told that as they get bigger, they might get a bit aggressive. I've been having the most fun with the plants lately. Now that they are growing well, I just keep adding more. I really don't like the castle thing, but my wife likes it. Because it's white, it seems to be an algae magnet. I don't get a lot anymore, but it seems to appear on the castle only a few days after sanitizing it. I clean the glass about once a week, but the algae on the glass is very minimal.

I guess the only thing I wish I could do is completely eliminate algae growth. Is that even possible?
