The CYA level is going to drop as you drain water from the pool, so immediately after you refill you should see what difference you're going to. And yes, by using the tabs, you were increasing the CYA level, at a fairly fast rate.

If you only drain a foot and refill that won't make much of a difference to the CYA and you will have to repeat the process many times which is not very effective. I would bite the bullet and drain at least 3/4 of the pool. Make sure your water table is not high as you said you have a glass pool. 7,500 gallons should not cost you that much money. Like the above posters said use bleach from now on.
