Sit back, take a deep breath, and re-evaluate. Yep. Been there done that. There is a fairly steep learning curve with a high-tech tank, and getting everything balanced to where it isn't
so much work when you really don't know what you're doing to begin with can be a royal pain and very stressful for what should be an enjoyable hobby.
I get just as much enjoyment from my 10 gallon low-tech as I do from the pressurized CO2 AHsupply kit 2wpg eco-complete substrate yada yada yada high-tech 55. I probably spent less than $50 on the ten gallon, and that was including the $20 I spent on the 18 watt work light for the lighting! Of course I did have a bunch of the stuff lying around already which cut down on the price considerably. There's a link to a pic in my sig.
Basically all I do to this tank is throw some fish food in every day and haul out some java moss occasionally (which is way overdue, pretty soon the fish aren't going to have anywhere to swim
!) No ferts, no CO2, tiny bit of algae I can live with. While plant choices are more limited of course, it grows Java Moss and Fern just fine, there's a couple of happy crypts, and even some HC in the foreground. Although the latter seems happy enough it is growing v*e*r*y s*l*o*w*l*y. But it is
I think sometimes we get carried away with the high-tech aspects of the hobby and forget that it isn't the only way to go.
Good luck with whatever you decide to do.
