Easy enough to move the live stuff into a plastic tote for a fews days to a week with your filter running on it to keep 'em going while you break down the tank and set it back up with new substrate (minus MTS) and spend a little time cleaning up the dw. Always nice to have a spare tank around for holding/growing out clippings, quarantine for new fish etc. Set it up as a low light tank with anubia or java fern on that driftwood and you won't notice or mind any remaining tannins as much and won't need to do much of any maintanance.
