The new tank I'm working on will be South American fish, but I have not tried to do the same with the plants. I kind of looked at it, but honestly, I'm not sure the natural environment these fish live in will have as many plants as I'm going to have in my tank. So, this is where I the idea of what I want the tank to look like deviates from nature.
Is the difficulty finding plants you like that will work in the regional tank or keeping them alive? I have been really lucky with plants over time- I've never had too much trouble with them, except for one time when I tried a cheap CO2 method. I was not consistent in the application of the CO2 and I was not consistent in maintenance- that created a disastrous amount of black beard algae and whatever else- had to yank all the plants and hardscape and start again that time.
I'm not taking chances on the new tank, though- I've purchased a good CO2 setup and have done a lot of reading- I think I'm going to use the Estimative Index (EI) method to fertilize. Basically alternate fertilizer types with large doses 6 days a week and then 50%-75% water changes once a week (no fertilization that day). I THINK that will make it easier to keep the plants the way I want them- I'll have to trim them a lot and all that, but won't have to worry as much about them melting.
My 15 gallon has no CO2, but I do kind of overfeed, which does provide CO2. I started to get some black beard algae on my anubias plants, but started fertilizing with API root tabs and API Leaf Zone in the water column. I happened to have a bottle of it laying around that I bought a couple of years ago, so started using it. No real reason other than that.
For the new tank I'm going to make my own fertilizer
using a recipe found on this site. Cheaper over time, and something else to fiddle around with.
I haven't looked at other fertilization methods, though. I saw this one and figured it would work for me, so I haven't looked further, but there are a bunch of other ways to go about it.
Anyway, the answer to your question is no, but I did think about it and above is what I decided to do instead. I did read that plants are harder to keep than the fish- I can see how that's true. I spend more time messing with them than I do with the fish by far.
