Keep testing for NH3
, they should eventually be undetectable. NO3
will typically rise up some but that is of no concern. Best suggestion is add the same amount of food every few days you would as if a fish was in there. If the biofilter is healthy, you should only see a change in nitrates, the other two should remain undetectable. Ammonia and nitrite generally show up in about 7-10 days so you should know by next weekend or sure.
