Is This A Newbie Question Or A Normal One

[lemond68]

If I am cycling a tank that I bought recently (where the old water was kept and the new water was "seeded" with a good squeeze of the old sponge) with my previous fish...

so far the readings were goodish...

Temp 75 F
pH 7.2
Ammonia 0 ppm
nitrite 0 ppm
nitrate 10 ppm

and i did a 50% water change. how quickly should I check the water quality again. i have not fed the fish and they seem good over the last 24 hours (one yoyo loach is not comming out much but otherwise looks ok).
Should I check immediately or in a couple of hours or tomorrow?

i am pretty obsessive about my water stats, so during cycling i usually check every day, and of course after every water change. once the system is stable, i just check after every water change (33%, weekly)
