Unless your bio load is very high in the freshwater column - you should not have to worry about accumulation of excessive nitrate-nitrogen and phosphates with regularly scheduled water changes.
CO2 exchange at the surface of the column is more than adequate with recommended livestock loading unless you heat your room with an unvented natural gas heater, for example. A simple outside air supply line to a small 1000 lph downdraft fractionator will solve this.
Then plant to your liking with synthetic plants and don't worry about what your tricolors do.

yeah, but we can be lazy with water changes & the live plants just suck it up...plus they look awesome...
i only have fake plants in my aquarium so the bala sharks can't eat anything. they do like to eat the algae off everything though, and make quite a bit of noise when they come up for food.
Trickle towers supposedly reduce nitrate levels, but I have no idea how they work. Honestly, people get the results, but I can't see how science can explain it.

Trickle towers may reduce nitrite levels but not nitrate levels - UNLESS:
It's a blowoff design - very tall, narrow columns filled with rather open media that has the water blown at high velocity generating a lot of downdraft. These are called ammonia towers and rid the input of excessive ammonia BEFORE nitrosomonas can begin the breakdown process. Less capable designs (the downdraft skimmer so many reefers use - see Bingman and Lohr in the patent books) will indeed remove phosphates (and other trace elements as well!)
Neither hardware is really associated with the novice particularly freshwater aquarists, but it's a fun thing to discuss.

I must admit, you're a polymath.

I wonder if it's possible to use a modified version of Jaubert's NNR to work in freshwater beds.

one snail. Why the anti-undergravel filter snobbery?
Our fish are all very healthy, and we're using an undergravel in the big tank...One the live plants front, for whatever reason we noticed our fish looking much happier/healthier in the weeks after we chnaged from plastic to live plants...

If the plenum resides within the same physical vessel as the livestock then yes - that is scary.
Ditto for UGF's.
A rotating aerobic biological contactor has tremendous capacity for ammonia/nitrite removal in a small area. The half immersed drum gives a good mix of fresh air and contact with water too. Some confined areas will use freshly supplied air within the enclosed space provided by banks of regenerative blowers but we're talking medium (400 gal/min) setups and higher. The Marineland Bio Wheel OPF is a scaled down version of this concept and has generally positive feedback from beginner and experienced aquarists alike.

dammit! why the UG snobbery?
put a little wire cage around the plants, so the sharks can only nibble on the leaves that poke out through the holes in the wire
pics of the baby sharks?
