i would have gone with removing all the water, ... maybe twice just to make sure any residual stuff was gone.
crzy, a % thing
removing 50%, and another 50% , and another 50% is still 12% remaining of whatever it was
removing near all (say stuff in the substrate is hard to remove - so 90%)
removing 90%, and another 90%, that's like 1% remaining isn't it ?
keeping the tank filled over-all in the attempt at keeping the bacteria alive to avoid cycling again.
for what to put in the tank
while i think 10 gallons is too small
i like the cardinal tetra, and the green neon looks nice too (both are small)
