You can do that if you like, but you ought not recommend it to other folks, for at least two reasons: If you try that technique in a plaster pool, the acid will settle to the bottom and do irreversible damage to the plaster. Lowering the TA is not the main goal for most people. In a high TA...

That's a big part of the problem. I reckon that means every time you add 250 gallons of such water, you need to add a pint of concentrated (34%) acid just to break even. If you want to lower the pH and/or TA, you have to add more acid than that. Test the acid demand, and add the indicated...

The best solution is the simplest: If you see an oil slick forming in the skimmer, ladle it out into a bucket and then pour it down the drain. You don't want to use chemicals. That would only cause the oils to mix with the water, which is not where you want them. There are about ten reasons...
