I have a 30g long tank that I want to use as a low light, no CO2 community tank. I am going to retrofit the light to a 72w PC and use EcoComplete as substrate. All I really want to keep is some Java ferns, an Amazon Sword and maybe some Anubias plants. Haven't decided on the livestock yet but I'm thinking 10-15 neons, a few cories and a few golden wonder killies. Does it sound like this will work? I want to run CO2-less if at all possible. I realize the plants may not thrive but I just want them to do well.

I think this would be more successful with less light. 72W PC light is still pretty strong for a low maintenance setup. Might work, or you might find yourself struggling with algae, and starving plants.

Not sure if you can find something in the 45 - 55 Watt range, IMO that would work better without CO2.

Fully grown Golden Wonders might be big enough to gulp down Neons, not sure, but to be safe I would go a step up from Neon size.
I was wondering if 72w was too much for non-co2. I may try lower, there is a 48w also. The killies weren't set in stone, I would rather have a small school of small schooling fish than a few big ones. Thanks for the tips, what do you think about the A. sword?

Amazon sword will be nice for the low tech tank. Just remember to trim it here and there if it starts to get out of control (and it most likely will:hihi: )

I would also recommend getting a lower light like a 48w. maybe like a 60watt but I'm not sure there is a fixture that would work for your tank in that range of watts lol...

I would go with 48W on a 30L. I have a 36W T-5 over my 29G set up and the light is very bright. I've never had any algae problems at all, but I do have DIY Co2 . With over two wpg and no CO2 your asking for trouble.

heres a link to my low tech tank setup:

BTW, if I order the 2x24w system should I get both the bulbs in the 10,000K?
Or mix in a 50/50?
If you want to do a salt water tank get a 50-50 bulb. If you want to grow plants and have them look reasonably natural, don't use a 50-50.
You could mix a 6700K with that 10000K bulbs. It's a nice color mixture. All 10000K makes some of the light green plants look washed out.
i've got 72 watts (2x36) over my 30 gal. i had to use co2 for an 8 hour photoperiod. did diy, but was seduced and eventually succumbed, to pressurized.

now my interests are going toward low light and low tech (no carbon, ferts when i remember, no water changes). these tanks do look nice when finally "balanced" and end up being much more enjoyable with much, much less work.
I had a 28W light over my 30 G tall in a non-CO2 set-up with Eco and peat for a substrate. My Anubias and Java Ferns did very well. The Java Fern started out as a straggly 3 leaf mess. After about 6 months it was overwhelming the medium sized piece of driftwood that I had attached it to. My Anubias frequently put out new leaves and even produced a flower type structure once. Good luck with your tank.
