I've asked here before, but I've got some more advanced questions now that I've gotten started. Just to brief on what my aquarium setup is, I have a 20 gallon long with some java moss and amazon sword. Once I move my tank back to its normal stand, I'll be setting it up with a DIY CO2 injector. Also, I'm only at about 1.1 WPG at the moment. I'll be getting a stronger light, but I'll discus that later (haha get it?) If the picture loaded, you'll only be able to see the sword. That large structure in the back is some plastic material I'm assuming, and am curious what kind of plants I can attach to that (it was expensive and I want a forest tank eventually, so I want to keep it in there). With the CO2, I cannot afford a "real" system. So I would use the 2 liter bottle + yeast etc. version, but I was informed about a liquid chemical that I can use instead... What's your opinion? I am having trouble finding a good 24" light for my tank that would put me above 2 WPG. So I was considering using clip on LED's on the back or something. Like the CO2, I can't afford to buy a different hood with more than one socket. How should I solve my lighting problem? Well, the technical problems explained, I am looking for some plant types. I'd prefer hardy, low maintenance (except trimming, I am talking about fertilizers, etc) plants. So I would like 1-2 low, carpet type plants. I have my java moss already. Then I'd like one or two types of bushy plants, one of which I'm thinking is a java fern. I've got the sword already two. Then, lastly, I'm looking at a few types of long stem plants, if you get what I mean. Any ideas? I'm completely open to suggestions. Thanks in advance, sorry for the wall of text.
