Testing after PWC

[sooju]

How long after a PWC do I need to wait before testing water parameters? A few hours or next day?

At least 24hrs if not 48hrs.

I agree with the 24-48 hrs but it would not be a bad idea to every so often to check your PWC water to make sure you are not adding anything bad to the tank.

I check the PWC water every change to make sure the levels are where I want them. I usually need to increase Ca before adding.

Heck, test it now and in 24 - 48 hours IMO. Part of the learning. Let us know what you find out.
