I thought you said your P04 was already zero, so how could you be stripping P04 from that??

Are you sure it was zero? Are you using a Hanna Checker? The color test kits will show zero long before the Hanna. The color kits can show zero while the Hanna will show .1 or higher. Then indeed you have to be careful not to lower too fast. But you still want to lower it, just more slowly.
