Well so you can get an Idea of what it will cost to get a planted tank similar in size to yours running.
$280.00 on my tank and stand setup. (I feel like I did alright on that aspect, I know some spend hundreds...)
$145.00 on my Eheim 2217
$120.00 on Odyssea quad t5 with plant lights.
$100.00 +/- on sand. (bio-active Cichlid sand)
$40.00 on heater.
$60.00 on driftwood.
$35.00 on a powerhead-circulation pump.(real low setting)
Then you need to stock with fish and figure out which plants you will use. I have about $150-200 in fish and probably $30 in plants to date. But I have been adding a few plants every week.
Roughly $1000.00 in my current setup before food, fertilizers (wet-dry) and other miscellaneous items that we all know I am missing.
65 Gallon Tall 4' long Planted aquarium, Eheim 2217
Stock: 6 Roseline's, 6 Peppered Corys, 4 Oto's, 5 Giant Danios, 4 Rosey Barbs, 2 Ruby Rams-Male-Female, 1 F German Ram, 2 Dwarf Gourami, 2 Angle Fish, 3 shrimp.
Hey I just did my tank on a budget... few things
A low/med tech light varies in price $60 - $200. Oddysea Lights new (for a 108W set up) is $60 shipped. So depending on the value of your fish and the brands the guy has it may be a decent trade.
New bulbs for a 48" range $10-$25 each.
Substrate: I used turface hertiage red, a $20 bag did my entire tank and looks/works great for the plants so far.
Ferts: All I use is Seachum Flourish Root Tabs
My Light: I did a DYI CFL set up, cost me $40 total and was easy, plus completely customizable
Plants: I probably couldn't grow and sort of carpet, unless it was a simple moss, but my plants have all been doing well (except the amazon sword)
While this can be expensive, it does not need to be.

Okay, Ill be willing to spend however much on the tank really, probably just like $700 a month so while I am cycling the tank I should be able to stock up on everything I need. All together I think I will probably end up spending more than $2,500 on it now that I have more money coming in.
I have also decided to do the planted tank in a new tank so I will be keep the 300L I have now as a cichlid tank because I do quite like them and have been meaning to get another tank anyway :-)
Now comes the excitement of finding a new tank!
