Ned,
Do not worry so much and do not give up. I think that you have a very good chance of waking up tomorrow and living thru the day. What do you think? When was the last time you did not wake up or survive the day? I think your odds are pretty good and I'm rooting for you.
Plus, I'm not trying to prevent a sale for you. I was being sarcastic about using the danner's, but I guess that text doest show your emotions very well.
Alex,
You'll need the aquaclears in the meantime while you build your custom setup. Your project will probably take twice as long as you expect it to and you'll probably change your design midway thruough because you didnt think of everything that could possibly go wrong. At least that is how my projects always go. Expect to make extra trips to the harware store also, or buy lots of extra parts. This is why aquarium equipment cost so much money. It can save you from a massive DIY nightmare.
If you buy the aquaclears from Ned, he will probably give you a lot of excelent free advice and ideas for you custom setup. While your out near neds, I would suggest going to "worms way" they are a hydroponic specialty shop about 20 min from neds and the have a website that you can look them up at. If your going custom, then I would recomend going hydroponic. Just make sure you take the humidity into account.
