i added four new tiger barbs a couple of weeks ago. Today water test as follows: nitrite 0, nitrate 0, pH 8.0, ammonia .25. So i did a 8 gallon h2o change. How long do these mini cycles last?: Should i keep checking ammonia everyday or every other day.

It's hard to say how long as it varies, but I'd do a 25-40% pwc every other day and test right before doing each change until you get 0 on ammonia.
