Hmm. I last moved the tank five months ago. It's so small that I was able to move it keeping all the plants in place with about 1/3 of the original water. I did probably half a dozen 1/2-inch gravel siphons during the weeks right after I set it back up to clean up all the stirred up mulm and have been keeping a close eye out for accumulating organics. I haven't done any massive water changes for five months now. It seems like the tank should have stabilized by now.
I'll try the root tabs but I really don't want to have to fertilize the tank - that's why I switched from high tech in the first place.
I don't think I can really add more stock as the tank kinda of does that all by itself
. It's currently stocked with least killifish and dwarf crayfish.
