DIY rimless 4.5 gallon (need light suggestions)

I made this out of glass I had from some broken 10 gallons.

So far the light is a 13W CFL, the substrate is pool filter sand.

There is some java moss, jern, and the stems are Rotala rotundifolia


Should I increase the light intensity? The tank is 12" tall, the light is about 2" above the tank.

Also, what can I use as a filter? The red sea nano seems like it would work well, or I could get a hagen mini elite. I'm probably going to start using DIY CO2, so the mini elite would work well for diffusion.
Right now I've got a small powerhead with a sponge on it, but it is too bulky.

No plans for fish right now, I might get some shrimp though.

On my 5g I switched from a redsea nano to a aqua tech 5-15 filter.
After a couple of months I was getting some mulm build up on the substrate and was not pleased with the flow at all from the redsea.

The redsea nano pushes 15 gallons per hour.

The aqua tech pushes 100GPH.
I covered the outlet stream with a very coarse sponge to lower the current it created.

I am sure you are aware that 6500k temp range bulbs are a good choice. I used 2 15wt spiral CFL's on my 5g and it worked well with diy co2. I was able to grow glosso carpet and hair grass. After I switched to pressurized I upped the light to 52watts. But I also do not have any reflector and the bulbs are laying on there side. Which considerably lowers there lumen output.

Hope that helps

That is one cool looking driftwood. I think 13w would be ok if you stick with the ferns and moss but might be cutting it close to the rotala just because its a higher tank. Let's get a filter in and see some clear pictures of that awesome driftwood.

Narrow or needle leaf java fern as the background imo if your going low tech.

Currently out of the hobby

I replaced the bulb with a 23W 6500k. I also put some osmocote under the sand. So far it hasn't raised the ammonia (I did a test with osmocote in a cup of water, and it raised it pretty quick, but in the tank it is more diluted plus under the substrate)
No fish or invertz, so it doesn't matter anyway.

The Rotala has definitely grown, and the moss is slowly expanding. I put one sad little E. tenellus in there and it has sprouted a new leaf.
