Can you explain the importance of the airation? I know it is important, but what exactly is the airation doing for the water? Mixing it up?
The aeration is mixing the salt and bringing the O2
level up to saturation. If the SW
is loaded with CO2
and has little O2
will be very low and the swing that causes when it is introduced to your tank could be very harmful to your fish and inverts
I only add 5 gallons each water change - couldn't I just pick up the 5 gallon jug and shake it for a few moments?
If you shake it up, it will not mix O2
into the water, unless it is open, but if it's open and you shake it up....your gonna get wet
