Nope. Aerating remove carbonate alkalinity, not calcium hardness.
The only way to remove hardness, is to precipitate it. And, with CH=1000, that's something to consider. Read this post on removing calcium: http://www.poolforum.com/pf2/showthread.php?16992
Meanwhile:
1. Get a K2006. Test kit info page link in my blue signature block.
2. When you have the kit, test BOTH your pool water AND your fill water.
3. Report results here.
PS: Lower your alkalinity will reduce the liklihood of scale formation -- so it's worth something. But it would be better to lower alkalinity AFTER removing calcium.
