Thank you for the nice compliment I guess I am just shy about my aquarium.

When I see the great work here I feel like a newbie. If I could do 20 or so aquariums I would start to understand aqua-scaping. I have Amano's books and Walstad's book and their level of work is out of my league. I am simply a newbie.
The tank is 29 gallons, 20 watts of substrate heating and 55 watts of light with a very nice reflector. It is one of these kits and I am very happy with it:

I am using a Jungle CO2 system. It is little fizz tabs to fill a reservoir that you can see in the back of the tank. Here is a link:

When I run out of fizz tabs I am either going to make my own tabs or bring a CO2 bottle home from work. I am not willing to buy a pH dosing system. I like the idea of making my own CO2. Even though I keep yeast at work and a yeast based system would be easy for me but it would remind my of work. (My day job is a brewer in a brewery.) I could keep the little reservoir and just fill it in the mornings from the bottle. Once the reservoir is full it lasts for about 4 hours. This is much like the CO2 levels in a lake. They are usually depleted by noon.
So I would call this DIY CO2 and medium light. I have checked the pH and I have very little CO2 most of the time. I strive very hard to have rapid plant growth as I think it is the best defense against algae. So for (knock on wood) no problems. I do have an apple snail and 2 zebra nerites in there on clean up patrol. I try to leave old leaves around for the apple snail. If there aren't any I add canned spinach. "Gary" loves the canned spinach.
I need to make some changes to my filter (Whisper 30) and then I want to get some Amano shrimp. I have some in my 10 gallon but I had to ditch the filter as I kept finding their bodies in there. Now my 10 gallon is running filter-less with a little power head to move the water. No shrimp casualties since.
One think I really learned from all of this is CFLs are not as efficient as a tube with a good reflector. My 10 gallon has 26 watts of CFL and the lights are much closer to the substrate. When I move most plants to the 10 gallon their growth slows. Some are a little faster but most have slowed. I have been planting the 10 gallon with cuttings from the 29 gallon.
And plant red plants in the brightest places in the tank. They need more light. I love red plants though.
Also, find an old copy of "The Optimum Aquarium". I found a used one for $8 on Amazon. It has some good tips. Although the writing style is a little pretentious for me. Or perhaps pedantic is a better word. Or really both apply.
