How to Mix Synthetic Seawater in Under Five Minutes

Brad, if you have tested short term rapid mixing pH change compared to longer term (overnight, for example) mixing pH change and the results are pretty much the same, I'd say stick with your current practice.

But others out there are quite possibly assuming rapid pH changes are happening during their own particular mixing process when it is not. Testing pH change in short term mixing vs. longer term mixing is the only way to know for sure what pH is actually doing.

I'm not really into this rapid mixing thing. Too much work. Easier to put in the powerhead and heater and leave this equipment work while I have a good night's sleep

As a point of interest, here is Epcor's On-Line Tour of a Water Treatment Plant. It details all the processes untreated water (in our case, water from the N. Saskatchewan River) goes through to get to our taps:
