OMG this is what I was thinking about! NO WATER CHANGES! This is genius!!!
Hello AA...
Guess this thread wouldn't be complete without a pic of an experimental tank. This one's been running a few months with nothing more than some emersed land plants to keep the tank water pure.
Got tired of removing and replacing half the tank water every week, so these plants now do the work of the water changes. Have the standard filtration, but the plant roots take in the nitrogens faster than my good bacteria.
Anyway, the tank is essentially maintenance free.
