I'm in Clarksville too and new to the hobby of the planted aquarium. I've been keeping fish for years and even had a saltwater reef set up once upon a time. But, got a 55 gallon today. (whole set up, tank, stand and lights in great shape for 100$ on craigslist woohoo!) My husband and I have decided we want to focus more on the planted aquarium and are just starting out. We also have a 29gal with some baby tears and swords. None of them have been looking that great so when we were looking for ways to resolve this and routes to take with our new tank, we came across this site. It looks like it has massive amounts of info. Good luck with your tank!
Welcome, and it's nice to have another local on the forum.
Nice find on the 55g, they are a good size tank to start with. Gives you a good amount of floorspace to plant.
Swords are great plants and can get huge, but they are heavy root feeders. Put some root tabs down for the swords. You can buy them at the lfs or you can get home made on here in the power seller section for a much better price. Baby tears pretty much need co2 to survive in a tank. I'm sure there are people who have had luck without injecting, but you will have less headaches if you give it what it wants.
On the 29g you can get away with DIY co2, but anything bigger it gets to be more of a hassle and cost than it's worth. I tried diy on my 125g and it didn't really do anything but take up time I could do other things. I have since switched to compressed on that tank. The only tank I am bothering to use diy co2 is my wife's 15g. If you have any questions by all means ask. I will do my best to answer or find your answer.
I will be happy to help you get going by donating some plants in a few weeks when my tank takes off again.
Welcome to the forum!! If you want to have someone close by for any advice, I am here. I have also met with SlammedDC2 and got to look at his gorgeous tanks as well as ask a ton of questions. He is super nice and easy to talk to, and experienced in plants and all. I'm sure you will find plenty of help, but having people in town is a great advantage too!!
Aww, why thank you. BTW both the 55 and 125 have changed quite a bit since you were at the house last week.
