When the other member asked if you cycled the tank for only a week I believe they were alluding to the fact that you can’t cycle a tank that fast without using already seeded media.
did you use already seeded media? Or do you mean you let water run through your filter for a week?
if the answer is running Water for a week, then no, your tank is not cycled. You have no bb built up in your filters to process fish waste. Especially if you have not been adding a source of ammonia for the week you thought it was cycling.
please take a look at this information for cycling your tank:

When you say your water parameters are good do you mean you tested them? If so did they read as follows?
Nitrites 0ppm
Ammonia 0ppm
Nitrates 0ppm
if the answer again is yes, you are not cycled and those are not good parameters.
for a cycled tank you will have 0 ammonia and nitrites and something registering as nitrates. Ideally you want to keep your nitrates below 20ppm between water changes.
if you did use seeded media then good for you! Your well on your way to a cycled tank. You will still have to monitor your water parameters and do water changes accordingly. The bb will need some time to adult to the new stocking levels.
