Testing

[Mr tooheys]

How long after a water change should I wait before testing water???

I usually wait about 2 hours.

I would wait about 3 days and see how much calcium, alkalinty and magnesium is being consumed so you can determine what amount you need to dose to keep levels stable. Once you do this divide by 3 and then go to brs calculater and it will tell you how much to dose.
