Any good lists/websites with bog plant species that you used, or did you just use trial and error?
Check the Riparium section and specifically threads/posts by Hydrophyte. A wealth of information regarding suitable plants. Also there's a thread by BigTom in which he set up a similar tank and tried out a few houseplants to see which worked. I think a few Calathea Sp.
The planters with hydroleca actually have no nutrient value and I think the plants are starting to suffer as they grow and increase demand for nutrients. The peace lilly has rooted way down through the basket and almost to the substrate and 3/5 planters have been switched to some year old ADA Amazonia 2 in an effort to provide more nutrients to the roots. Maybe if I was dosing the water column I wouldn't need to do this.
As for Philodendron my P.Scandens was growing well but I decided to remove it as I didn't like the look.
