Yeah I plan on doing a lot for these tanks when I have the money for it. replacing substrate, adding potting soil, more variety of plants. the setup has changed since this recording. there are more snails that need to be culled as they're overpopulating. Water changes every few months really needed and I don't gravel vac just hover over the substrate. Also the occasional water top offs when needed. it's pretty walstrad minus the filters in and on the tank.
