Testing question

[RogueGrown]

If I do a water change how long should I wait before testing??? Is it the same as if I dose say calcium and wait 8-12hrs before taking a test or am I ok after a good 1/2hr of mixing? After all there isn't anything to settle.

I'd like to have the most accurate results I can.

Dosing or water changes either or 2 hrs should be plenty of time to test. Most are turning 20-50times the volume of water in 1 hr.

It depends a bit on the turn over in the tank, the turnover from sump to tank assuming you have a sump. In most tanks water is mixed much faster than you would imagine. IMHO, 30 minutes is more than long enough unless you have really slow turnover.

At the moment I have no sump and am about 35 times an hour.

So the tank turns over every couple minutes. Just do your additions in a high flow area, and it shouldn't take much time for everything to thoroughly mix. I would think a half hour or so would be plenty safe.

30 mins to an hour and you should be set.

Test at every 10-15 minutes until the results stabilize and then you will know.
