I agree whole heartedly, AERATE, AERATE, AERATE.

Found out the hard way, when first setting up my tank.

PH= 7.3 with Instant Ocean salt mix. I thought it was a bad batch(or so I was told) but mixed it with powerhead only.

I proceeded to make a test batch to check if it was bad, but this time I used a powerhead and an air pump/stone and the PH=8.3.

From talking to others, it has something to do with carbon dioxide been released to bring the chemistry of the water in check.

I'm in no way an expert, just what I was told.
