1500 may be a bit high for Magnesium. Here is a link to natural sea water parameters. I try to keep mine as close to NSW as possible.

very little evidence to find substantiating that a high magnesium level has any affect on anything.

So how would I go about aerating the whole tank. I'm running an ASM G-3 right now so maybe stick the air intake outside somewhere? Would that be sufficient enough?

I have three power heads on a variable timer to increase the flow rate and type(turbulent) especially on the surface area. This gets rid of any stale air layers that can build up which can hamper air exchange.
Probably the best area of exchange is through the protein skimmer---crank it up
If the sump is not out in the open--eg under a cabinet--keep the doors open for a period during the day.
Make sure you have good air circulation in the house--I'm from the great white north--we have furnaces--i keep the air blower on 24/7 even with the airconditioning.

my skimmer is way oversized for my size tank so why am I having air exchange problems?

 

[bertoni]

If the air going into the skimmer is high in CO2, the pH of the tank will be lower. High indoor CO2 levels seem very common. Can you open a window or otherwise provide more fresh air for a day or so, or perhaps a few hours, as an experiment?

Ill try buying some more hose and putting the skimmer intake under the house somehow...ill let you know what happens later

 

[bertoni]

That approach sometimes works. Often, though, the skimmer input isn't enough to offset the other aeration surfaces.

Here's what I did: the main tank is upstairs directly overhead(the smaller tank in the pic is just a quarantine/frag/everything tank
